Der Begriff "Schalteinheit" soll hier insbesondere eine Einheit definieren, die zumindest ein Bauteil, insbesondere das Schaltklinkenelement, aufweist, das direkt von einem Bediener betätigbar ist und die dazu vorgesehen ist, durch eine Betätigung und/oder durch eine Eingabe von Parametern einen Prozess und/oder einen Zustand einer mit der Schalteinheit gekoppelten Einheit zu beeinflussen und/oder zu ändern. Das Schaltklinkenelement ist vorzugsweise zu einer Betätigung zumindest eines Schaltelements der Schalteinheit vorgesehen. Unter einem "Schaltklinkenelement" soll hier insbesondere ein Bedienelement verstanden werden, das entlang einer Längserstreckungsrichtung des Bedienelements eine Längserstreckung aufweist, die größer ist als eine zumindest im Wesentlichen senkrecht zur Längserstreckungsrichtung verlaufende Quererstreckung des Bedienelements, die zumindest im Wesentlichen quer zu einer Hauptbewegungsrichtung des Bedienelements verläuft. Insbesondere ist eine maximale Längserstreckung des Schaltklinkenelements zumindest 2-mal größer, bevorzugt zumindest 4-mal größer und besonders bevorzugt zumindest 6-mal größer als eine maximale Quererstreckung des Schaltklinkenelements. Das Schaltklinkenelement weist insbesondere eine maximale Längserstreckung auf, die größer ist als 3 cm, bevorzugt größer ist als 6 cm und besonders bevorzugt größer ist als 8 cm.The term "switching unit" is intended here to define in particular a unit which has at least one component, in particular the pawl element, which can be actuated directly by an operator and which is provided with a process and / or by inputting parameters or to affect and / or change a state of a unit coupled to the switching unit. The pawl element is preferably provided for actuating at least one switching element of the switching unit. A "pawl element" should be understood here to mean, in particular, an operating element which has a longitudinal extent along a longitudinal extension direction of the operating element which is greater than a transverse extent of the operating element extending at least substantially perpendicular to the longitudinal extension direction, which runs at least substantially transversely to a main direction of movement of the operating element , In particular, a maximum longitudinal extent of the pawl element is at least 2 times greater, preferably at least 4 times larger, and more preferably at least 6 times greater than a maximum transverse extent of the pawl element. In particular, the pawl element has a maximum longitudinal extent which is greater than 3 cm, preferably greater than 6 cm and particularly preferably greater than 8 cm.

Ferner umfasst das Schaltklinkenelement bevorzugt eine Bedienfläche, insbesondere eine von einem Griffflächenbereich des Schaltklinkenelements gebildete Bedienfläche, auf der ein Bediener zumindest drei Finger zu einer Betätigung des Schaltklinkenelements anordnen kann und die zumindest eine entlang der Längserstreckungsrichtung des Schaltklinkenelements verlaufende Längserstreckung aufweist, die größer ist als 5 cm. Der Ausdruck "im Wesentlichen senkrecht" soll hier insbesondere eine Ausrichtung einer Richtung relativ zu einer Bezugsrichtung definieren, wobei die Richtung und die Bezugsrichtung, insbesondere in einer Ebene betrachtet, einen Winkel von 90° einschließen und der Winkel eine maximale Abweichung von insbesondere kleiner als 8°, vorteilhaft kleiner als 5° und besonders vorteilhaft kleiner als 2° aufweist. Unter "im Wesentlichen quer" soll hier insbesondere eine Ausrichtung einer Richtung und/oder einer Achse relativ zu einer Bezugsrichtung und/oder einer Bezugsachse verstanden werden, wobei die Ausrichtung der Richtung und/oder der Achse zumindest verschieden von einer zumindest im Wesentlichen parallelen Ausrichtung zur Bezugsrichtung und/oder zur Bezugsachse ist und insbesondere windschief oder senkrecht zur Bezugsrichtung und/oder zur Bezugsachse ist. Vorzugsweise ist die Schalteinheit dazu vorgesehen, mittels einer Betätigung des Schaltklinkenelements das Schaltelement zu betätigen, um einen Stromkreis zu einer Energieversorgung zumindest einer Antriebseinheit der Werkzeugmaschine zu öffnen oder zu schließen. Somit ist die Schalteinheit bevorzugt dazu vorgesehen, eine Inbetriebnahme oder eine Deaktivierung der Werkzeugmaschine zu ermöglichen. Unter "vorgesehen" soll insbesondere speziell ausgelegt und/oder speziell ausgestattet verstanden werden. Das Schaltelement wird bevorzugt von einem mechanischen, elektrischen und/oder elektronischen Schaltelement gebildet.Furthermore, the pawl element preferably comprises an operating surface, in particular a control surface formed by a gripping surface region of the pawl element, on which an operator can arrange at least three fingers for actuating the pawl element and which has at least one longitudinal extent extending along the longitudinal extension direction of the pawl element which is greater than 5 cm. The term "substantially perpendicular" is intended here to define, in particular, an orientation of a direction relative to a reference direction, the direction and the reference direction, in particular in one plane, including an angle of 90 ° and the angle a maximum deviation of, in particular, less than 8 °, advantageously less than 5 ° and particularly advantageously less than 2 °. Under "essentially "transverse" is to be understood here in particular an alignment of a direction and / or an axis relative to a reference direction and / or a reference axis, wherein the alignment of the direction and / or the axis at least different from an at least substantially parallel orientation to the reference direction and / or In particular, the switching unit is intended to actuate the switching element by means of an actuation of the pawl element in order to open or close a circuit to a power supply of at least one drive unit of the machine tool Thus, the switching unit is preferably intended to enable a commissioning or deactivation of the machine tool. "Provided" is to be understood in particular to be specially designed and / or specially equipped n, electrical and / or electronic switching element formed.

Unter einer "Bewegungssperre" soll hier insbesondere ein Sperrmechanismus verstanden werden, der dazu vorgesehen ist, zumindest in einem Betriebszustand eine Bewegung eines beweglich gelagerten Bauteils entlang zumindest einer Strecke und/oder um zumindest eine Achse mittels einer mechanischen, elektrischen und/oder elektronischen Sperre weitestgehend zu verhindern. Bevorzugt ist die Bewegungssperre dazu vorgesehen, zumindest in einem Betriebszustand mittels einer mechanischen Sperre eine Bewegung des beweglich gelagerten Schaltklinkenelements weitestgehend zu verhindern. Es ist jedoch auch denkbar, dass die Bewegungssperre zumindest in einem Betriebszustand mittels einer elektromagnetischen Krafteinwirkung und/oder einer permanentmagnetischen Krafteinwirkung, wie beispielsweise mittels verschiebbarer Magnete, auf das Schaltklinkenelement eine Bewegung des Schaltklinkenelements weitestgehend verhindert. Bevorzugt ist die Bewegungssperre durch das Freigabeelement der Schalteinheit entriegelbar, um eine Bewegung des Schaltklinkenelements infolge einer Betätigung des Schaltklinkenelements zu ermöglichen. Der Ausdruck "Betätigungsbereich" soll hier insbesondere einen Bereich des Freigabeelements definieren, der von einem Bediener in einem an der Werkzeugmaschine montierten Zustand des Freigabeelements zu einer Betätigung bzw. zu einer Bewegung des Freigabeelements direkt berührbar ist. Unter "seitlich neben" soll hier insbesondere eine Anordnung des Betätigungsbereichs des Freigabeelements relativ zum Schaltklinkenelement verstanden werden, wobei der Betätigungsbereich entlang einer zumindest im Wesentlichen senkrecht zu einem Seitenwandbereich des Schaltklinkenelements verlaufenden Richtung betrachtet, insbesondere ausgehend von dem Seitenwandbereich in eine von dem Schaltklinkenelement abgewandte Richtung betrachtet, relativ zum Schaltklinkenelement beabstandet angeordnet ist. Der Seitenwandbereich verläuft besonders bevorzugt zumindest im Wesentlichen senkrecht zu einem Griffflächenbereich des Schaltklinkenelements, der eine Grifffläche des Schaltklinkenelements bildet. Somit ist das Freigabeelement bevorzugt außerhalb der Bedienfläche des Schaltklinkenelements angeordnet. Besonders bevorzugt ist das Freigabeelement außerhalb des Schaltklinkenelements an der Werkzeugmaschine angeordnet. Mittels der erfindungsgemäßen Ausgestaltung der Werkzeugmaschine, insbesondere mittels einer Anordnung des Betätigungsbereichs des Freigabeelements seitlich neben dem Schaltklinkenelement, kann vorteilhaft eine ergonomische Handhabung des Freigabeelements realisiert werden. Ein Bediener kann komfortabel mit einer Hand das Schaltklinkenelement halten bzw. betätigen, während der Bediener mit einem Finger der Hand das Freigabeelement betätigt. Ferner kann vorteilhaft verhindert werden, dass eine Bewegungssperre des Schaltklinkenelements infolge einer unbeabsichtigten Betätigung des Schaltklinkenelements gelöst werden kann, da das Freigabeelement außerhalb der Bedienfläche des Schaltklinkenelements angeordnet ist.A "movement lock" is to be understood here in particular as a locking mechanism which is provided, as far as possible at least in one operating state, a movement of a movably mounted component along at least one path and / or around at least one axis by means of a mechanical, electrical and / or electronic lock to prevent. Preferably, the movement lock is provided to prevent a movement of the movably mounted pawl element as far as possible, at least in an operating state by means of a mechanical lock. However, it is also conceivable that the movement barrier, at least in an operating state by means of an electromagnetic force and / or a permanent magnetic force, such as by means of sliding magnets on the pawl element largely prevents movement of the pawl element. Preferably, the movement lock can be unlocked by the release element of the switching unit to allow movement of the pawl element as a result of actuation of the pawl element. The expression "actuating area" should in particular define a region of the release element which can be directly touched by an operator in a state of the release element mounted on the machine tool to an actuation or to a movement of the release element. In particular, an arrangement of the actuating region of the invention is to be understood here as "laterally next to" Released element relative to the pawl element to be understood, the actuating portion viewed along a at least substantially perpendicular to a side wall portion of the pawl element direction, viewed in particular starting from the side wall portion in a direction away from the pawl element direction, is arranged spaced relative to the pawl element. The side wall region particularly preferably extends at least substantially perpendicular to a gripping surface region of the pawl element which forms a gripping surface of the pawl element. Thus, the release element is preferably arranged outside the control surface of the pawl element. Particularly preferably, the release element is arranged outside of the pawl element on the machine tool. By means of the inventive design of the machine tool, in particular by means of an arrangement of the actuation region of the release element laterally next to the pawl element, advantageously, an ergonomic handling of the release element can be realized. An operator can comfortably hold or actuate the pawl member with one hand while the operator operates the release member with a finger of the hand. Furthermore, it can be advantageously prevented that a movement lock of the pawl element as a result of unintentional actuation of the pawl element can be solved, since the release element is arranged outside the control surface of the pawl element.

Des Weiteren wird vorgeschlagen, dass das Freigabeelement schwenkbar und/oder drehbar um zumindest eine Freigabebewegungsachse gelagert ist. Mittels der erfindungsgemäßen Ausgestaltung kann vorteilhaft ein komfortabel zu bedienendes Freigabeelement erreicht werden.Furthermore, it is proposed that the release element is mounted pivotably and / or rotatable about at least one release movement axis. By means of the embodiment according to the invention can be advantageously achieved a comfortable-to-use release element.

Erfindungsgemäß weist das Freigabeelement zumindest eine Freigabebewegungsachse auf, die in einer sich zumindest im Wesentlichen senkrecht zu einer Bewegungsachse des Schaltklinkenelements erstreckenden Ebene verläuft. Besonders bevorzugt ist die Freigabebewegungsachse als Schwenkachse ausgebildet. Somit weist das Freigabeelement vorzugsweise eine Schwenkachse auf, die in einer sich zumindest im Wesentlichen senkrecht zu einer Bewegungsachse des Schaltklinkenelements erstreckenden Ebene verläuft. Es kann konstruktiv einfach eine Anordnung des Freigabeelements relativ zum Schaltklinkenelement erreicht werden, die eine komfortable Bedienbarkeit des Freigabeelements, insbesondere eine komfortable Betätigung des Betätigungsbereichs des Freigabeelements, mittels eines Fingers einer Hand eines Bedieners ermöglicht. Somit kann vorteilhaft ein hoher Bedienkomfort erreicht werden.According to the disclosure, the release element has at least one release movement axis which extends in a plane extending at least substantially perpendicular to a movement axis of the shift pawl element. Particularly preferably, the release movement axis is designed as a pivot axis. Thus, the release element preferably has a pivot axis which is at least substantially perpendicular to a movement axis extending the pawl element extending plane. It can be structurally simple an arrangement of the release element relative to the pawl element can be achieved, which allows comfortable operation of the release element, in particular a comfortable operation of the actuating portion of the release element, by means of a finger of a hand of an operator. Thus, advantageously a high level of operating comfort can be achieved.

Zudem wird vorgeschlagen, dass die Schalteinheit zumindest ein weiteres Freigabeelement aufweist. Bevorzugt weist das weitere Freigabeelement eine weitere Freigabebewegungsachse auf, die zumindest im Wesentlichen parallel zur Freigabebewegungsachse des Freigabeelements verläuft. Hierbei ist die weitere Freigabebewegungsachse als Schwenkachse ausgebildet. In einer alternativen Ausgestaltung der erfindungsgemäßen Werkzeugmaschine weist das weitere Freigabeelement vorzugsweise eine weitere Freigabebewegungsachse auf, die identisch mit der Freigabebewegungsachse des Freigabeelements ausgebildet ist. Mittels der erfindungsgemäßen Ausgestaltung kann vorteilhaft eine komfortable Bedienbarkeit des Freigabeelements und/oder des weiteren Freigabeelements für Rechts- und für Linkshänder erreicht werden.In addition, it is proposed that the switching unit has at least one further release element. Preferably, the further release element has a further release movement axis, which runs at least substantially parallel to the release movement axis of the release element. Here, the further release movement axis is designed as a pivot axis. In an alternative embodiment of the machine tool according to the invention, the further release element preferably has a further release movement axis which is identical to the release movement axis of the release element. By means of the embodiment according to the invention can advantageously be achieved a comfortable operability of the release element and / or the further release element for right-handed and left-handed.

Vorteilhafterweise umfasst die erfindungsgemäße Werkzeugmaschine eine Bewegungsabhängigkeitseinheit, die das Freigabeelement und das weitere Freigabeelement zumindest in einem montierten Zustand bewegungstechnisch miteinander koppelt. Unter einer "Bewegungsabhängigkeitseinheit" soll hier insbesondere eine Einheit verstanden werden, die dazu vorgesehen ist, zumindest ein Element in Abhängigkeit einer Bewegung zumindest eines weiteren Elements zu bewegen, wobei das Element vorzugsweise entlang einer einer Bewegungsrichtung des weiteren Elements abweichend, und insbesondere entgegengesetzt, ausgerichteten Richtung, und/oder entlang einer der Bewegungsrichtung des weiteren Elements gleichgerichteten Richtung bewegt wird. Besonders bevorzugt wird die Bewegungsabhängigkeitseinheit von einer Mechanikbewegungseinheit gebildet, die das Freigabeelement und das weitere Freigabeelement mittels eines mechanischen Mechanismus bewegungstechnisch miteinander koppelt. Es ist jedoch auch denkbar, dass die Bewegungsabhängigkeitseinheit von einer anderen, einem Fachmann als sinnvoll erscheinenden Einheit gebildet wird, wie beispielsweise von einer Magnetbewegungseinheit, die das Freigabeelement und das weitere Freigabeelement mittels magnetischer Kräfte bewegungstechnisch miteinander koppelt. Mittels der erfindungsgemäßen Ausgestaltung kann vorteilhaft eine zumindest im Wesentlichen gleichzeitige Bewegung des Freigabeelements und des weiteren Freigabeelements infolge einer Betätigung des Freigabeelements oder des weiteren Freigabeelements erreicht werden. Ferner kann vorteilhaft eine komfortable Entriegelung der Bewegungssperre des Schaltklinkenelements mittels einer Betätigung des Freigabeelements oder des weiteren Freigabeelements erreicht werden, wobei vorteilhaft lediglich eines der Freigabeelemente zu einer Entriegelung der Bewegungssperre betätigt werden muss.Advantageously, the machine tool according to the invention comprises a movement-dependent unit, which couples the release element and the further release element with one another, at least in an assembled state. A "movement dependency unit" is to be understood here as meaning, in particular, a unit which is provided to at least one element as a function of a movement of at least one further element wherein the element is preferably moved along a direction of a movement direction of the further element deviating, and in particular oppositely oriented, and / or along a direction of movement of the further element rectified direction. Particularly preferably, the movement-dependent unit is formed by a mechanical movement unit which couples the release element and the further release element in terms of motion technology by means of a mechanical mechanism. However, it is also conceivable that the motion dependency unit is formed by another unit that appears appropriate to a person skilled in the art, for example by a magnetic movement unit which couples the release element and the further release element with one another by means of magnetic forces. By means of the embodiment according to the invention can advantageously be achieved at least substantially simultaneous movement of the release element and the further release element as a result of actuation of the release element or the further release element. Furthermore, advantageously a comfortable unlocking of the movement lock of the pawl element can be achieved by means of an actuation of the release element or the further release element, wherein advantageously only one of the release elements must be actuated to unlock the movement lock.

Des Weiteren wird vorgeschlagen, dass die erfindungsgemäße Werkzeugmaschine zumindest ein Handgriffgehäuse umfasst, wobei das Freigabeelement und das weitere Freigabeelement infolge einer Betätigung des Freigabeelements oder des weiteren Freigabeelements in eine dem Handgriffgehäuse zugewandte Richtung mittels der Bewegungsabhängigkeitseinheit in eine dem Handgriffgehäuse zugewandte Richtung bewegt werden. Unter einem "Handgriffgehäuse" soll hier insbesondere zumindest ein Gehäuse oder zumindest ein Gehäuseteilbereich verstanden werden, das bzw. der von einer Lagerung einer Antriebs- und/oder Abtriebseinheit der Werkzeugmaschine weitestgehend entkoppelt ist, wobei zumindest ein Griffbereich des Gehäuses oder der Gehäuseteilbereich, insbesondere ein als stielförmiger Griffbereich ausgebildeter Gehäuseteilbereich, von einem Bediener zu einer Handhabung der Werkzeugmaschine mit zumindest einer Hand zumindest größtenteils umgreifbar ist. Der Ausdruck "größtenteils umgreifbar" soll hier insbesondere eine Umgreifbarkeit eines Bauteils oder eines Bauteilbereichs mittels einer Hand eines Bedieners entlang zumindest mehr als 70 %, bevorzugt mehr als 80 % und besonders bevorzugt mehr als 90 % einer Gesamterstreckung eines in einer sich zumindest im Wesentlichen senkrecht zu einer Längserstreckungsrichtung des Bauteils oder des Bauteilbereichs erstreckenden Ebene verlaufenden Gesamtaußenumfangs des Bauteils oder des Bauteilbereichs definieren, wobei die Gesamterstreckung des Gesamtumfangs insbesondere kleiner ist als 40 cm, bevorzugt kleiner ist als 30 cm und besonders bevorzugt kleiner ist als 25 cm. Vorzugsweise liegen bei einem Umgreifen des Bauteils oder des Bauteilbereichs eine Handinnenfläche und Fingerinnenflächen der Hand des Bedieners zumindest entlang einer Strecke größer als 70 %, bevorzugt größer als 80 % und besonders bevorzugt größer als 90 % der Gesamterstreckung des Gesamtaußenumfangs am Gesamtaußenumfang an. Vorzugsweise ist der stielförmige Griffbereich, entlang einer Rotationsachse eines Antriebselements, insbesondere einer Ankerwelle, einer Antriebseinheit der Werkzeugmaschine und insbesondere entlang der Haupterstreckungsrichtung der Werkzeugmaschine betrachtet, hinter der Antriebseinheit angeordnet. Zudem ist es denkbar, dass das Handgriffgehäuse zusätzlich zum stielförmigen Griffbereich einen bügelförmigen Teilbereich aufweist, der einstückig an den stielförmigen Griffbereich angeformt ist. Der bügelförmige Teilbereich kann vorzugsweise eine L-förmige Ausgestaltung aufweisen, die sich ausgehend von einem dem Anbindungsbereich des Handgriffgehäuses abgewandten Ende des stielförmigen Griffbereichs L-förmig in Richtung des Anbindungsbereichs erstreckt. Bevorzugt ist das Handgriffgehäuse getrennt von einem Antriebsgehäuse der Werkzeugmaschine ausgebildet, das dazu vorgesehen ist, die Antriebs- und/oder Abtriebseinheit zu einer Abstützung von Antriebs- und/oder Abtriebslagerkräften aufzunehmen. Es ist jedoch auch denkbar, dass das Handgriffgehäuse und das Antriebsgehäuse einstückig ausgebildet sind.Furthermore, it is proposed that the machine tool according to the invention comprises at least one handle housing, whereby the release element and the further release element are moved in a direction facing the handle housing by means of the movement-dependent unit in a direction facing the handle housing due to actuation of the release element or the further release element. A "handle housing" is to be understood here in particular at least one housing or at least one housing part region which is largely decoupled from a bearing of a drive and / or output unit of the machine tool, wherein at least one handle portion of the housing or the housing portion, in particular a designed as a handle-shaped handle portion housing portion, at least for the most part is umgreifbar by an operator to handle the machine tool with at least one hand. The term "largely encompassable" is intended here to encompass, in particular, a graspability of a component or a component region by means of a hand of an operator at least more than 70%, preferably more than 80%, and more preferably more than 90% of an overall extension of a total outer circumference of the component or component region extending in a plane extending at least substantially perpendicular to a longitudinal direction of the component or the component region, the total extension the total circumference is in particular less than 40 cm, preferably less than 30 cm and particularly preferably less than 25 cm. Preferably, when gripping the component or the component area, a palm and finger inner surfaces of the operator's hand are greater than 70%, preferably greater than 80% and particularly preferably greater than 90% of the total extension of the total outer circumference on the overall outer circumference, at least along a distance. Preferably, the handle-shaped handle portion, along a rotational axis of a drive element, in particular an armature shaft, a drive unit of the machine tool and in particular along the main extension direction of the machine tool, arranged behind the drive unit. In addition, it is conceivable that the handle housing in addition to the handle-shaped handle portion has a bow-shaped portion which is integrally formed on the handle-shaped handle portion. The bow-shaped portion may preferably have an L-shaped configuration which extends from an end of the handle-shaped housing facing away from the handle-shaped handle portion L-shaped in the direction of the connection region. Preferably, the handle housing is formed separately from a drive housing of the machine tool, which is intended to receive the drive and / or output unit to a support of drive and / or output bearing forces. However, it is also conceivable that the handle housing and the drive housing are integrally formed.

Vorzugsweise weist das Handgriffgehäuse einen stielförmigen Griffbereich auf. Der Ausdruck "stielförmiger Griffbereich" soll hier insbesondere einen Gehäuseteilbereich des Handgriffgehäuses definieren, der in einer Längsschnittebene, in der sich die Haupterstreckungsrichtung der Werkzeugmaschine erstreckt, entlang einer zumindest im Wesentlichen senkrecht zur Haupterstreckungsrichtung verlaufenden Richtung betrachtet, eine maximale Erstreckung, insbesondere kleiner als 10 cm, bevorzugt kleiner als 8 cm und besonders bevorzugt kleiner als 6 cm, aufweist, wobei zumindest eine Bedienfläche des Handgriffgehäuses im Gehäuseteilbereich des Handgriffgehäuses angeordnet ist. Bevorzugt wird die maximale Erstreckung, betrachtet in der Längsschnittebene, von zumindest zwei parallelen Geraden oder von zumindest zwei um einen Winkel kleiner als 10°, bevorzugt kleiner als 8° und besonders bevorzugt kleiner als 6° relativ zueinander geneigten Geraden begrenzt, die von einer Außenkontur des Gehäuseteilbereichs des Handgriffgehäuses gebildet werden. Der stielförmige Griffbereich ist insbesondere zumindest um einen Winkel kleiner als 60°, bevorzugt kleiner als 40° und besonders bevorzugt kleiner als 30° relativ zu einer Haupterstreckungsrichtung der Werkzeugmaschine geneigt angeordnet. Besonders bevorzugt umfasst das Handgriffgehäuse zumindest zwei Handgriffgehäuseschalenelemente, die in einer Verbindungsebene miteinander verbindbar sind. Somit weist das Handgriffgehäuse bevorzugt eine Schalenbauweise auf. Es ist jedoch auch denkbar, dass das Handgriffgehäuse eine Topfbauweise aufweist. Das Freigabeelement und das weitere Freigabeelement sind besonders bevorzugt jeweils an einer der Handgriffgehäuseschalenelemente angeordnet. Mittels der erfindungsgemäßen Ausgestaltung kann vorteilhaft infolge einer Betätigung des Freigabeelements oder des weiteren Freigabeelements ein Einschwenken des Freigabeelements und des weiteren Freigabeelements in das Handgriffgehäuse hinein ermöglicht werden.Preferably, the handle housing on a handle-shaped handle portion. The term "stem-shaped gripping area" should in this case in particular define a housing partial area of the handle housing which, in a longitudinal sectional plane in which the main extension direction of the machine tool extends, along a direction extending at least substantially perpendicular to the main direction, has a maximum extent, in particular less than 10 cm , preferably smaller than 8 cm and particularly preferably smaller than 6 cm, wherein at least one control surface of the Handle housing is arranged in the housing part region of the handle housing. The maximum extent, viewed in the longitudinal section plane, is preferably limited by at least two parallel straight lines or by at least two straight lines inclined by an angle of less than 10 °, preferably less than 8 ° and particularly preferably less than 6 °, relative to one another the housing portion of the handle housing are formed. The handle-shaped handle region is in particular at least an angle of less than 60 °, preferably less than 40 ° and more preferably less than 30 ° inclined relative to a main extension direction of the machine tool. Particularly preferably, the handle housing comprises at least two handle housing shell elements which are connectable to one another in a connecting plane. Thus, the handle housing preferably has a shell construction. However, it is also conceivable that the handle housing has a pot construction. The release element and the further release element are particularly preferably arranged in each case on one of the handle housing shell elements. By means of the embodiment according to the invention can advantageously be made possible by pivoting of the release element and the further release element in the handle housing into it as a result of actuation of the release element or the further release element.

Vorteilhafterweise ist das weitere Freigabeelement spiegelsymmetrisch zum Freigabeelement angeordnet. Es kann somit vorteilhaft eine besonders ergonomische Anordnung des Freigabeelements und des weiteren Freigabeelements für Rechts- sowie für Linkshänder erreicht werden.Advantageously, the further release element is arranged mirror-symmetrically to the release element. It can thus be advantageously achieved a particularly ergonomic arrangement of the release element and the further release element for right-handed and left-handed.

Ferner wird vorgeschlagen, dass das weitere Freigabeelement zumindest einen Betätigungsbereich aufweist, der, bezogen auf eine sich zumindest im Wesentlichen senkrecht zu einer Bewegungsachse des Schaltklinkenelements erstreckende Ebene, spiegelsymmetrisch zum Betätigungsbereich des Freigabeelements zumindest teilweise seitlich neben der Bedienfläche des Schaltklinkenelements angeordnet ist. Es ist jedoch auch denkbar, dass das weitere Freigabeelement eine andere, einem Fachmann als sinnvoll erscheinende Anordnung relativ zum Freigabeelement aufweist, die eine ergonomische Bedienbarkeit des Freigabeelements und des weiteren Freigabeelements für Rechts- sowie für Linkshänder ermöglicht. Mittels der erfindungsgemäßen Anordnung des Betätigungsbereichs des weiteren Freigabeelements kann vorteilhaft eine komfortable Bedienbarkeit des Freigabeelements und/oder des weiteren Freigabeelements erreicht werden.Furthermore, it is proposed that the further release element has at least one actuation area which, with respect to a plane extending at least substantially perpendicular to a movement axis of the pawl element, is arranged mirror-symmetrically to the actuation area of the release element at least partially laterally next to the control surface of the pawl element. However, it is also conceivable that the further release element has another arrangement that appears appropriate to a person skilled in the art relative to the release element, which enables ergonomic operability of the release element and of the further release element for right-handed and left-handed people. By means of the inventive arrangement of the actuation area the further release element can advantageously be achieved a comfortable operation of the release element and / or the further release element.

Besonders bevorzugt sind das Freigabeelement und das weitere Freigabeelement relativ beweglich zueinander gelagert. Hierdurch können besonders vorteilhaft Bewegungen des Freigabeelements und des weiteren Freigabeelements infolge einer Betätigung des Freigabeelements oder des weiteren Freigabeelements in voneinander verschiedene Richtungen ermöglicht werden.Particularly preferably, the release element and the further release element are mounted relatively movable to each other. As a result, movements of the release element and of the further release element as a result of actuation of the release element or of the further release element in directions which are different from one another can be made particularly advantageous.

Ferner wird vorgeschlagen, dass die Werkzeugmaschine zumindest die Bewegungsabhängigkeitseinheit umfasst, die dazu vorgesehen ist, infolge einer Betätigung des Freigabeelements oder des weiteren Freigabeelements das Freigabeelement und das weitere Freigabeelement in entgegengesetzt gerichtete Richtungen zu bewegen. Es kann vorteilhaft bei einer Anordnung des Freigabeelements an einer dem weiteren Freigabeelement abgewandten Seite des Handgriffgehäuses infolge einer Betätigung des Freigabeelements und des weiteren Freigabeelements eine Bewegung des Freigabeelements und des weiteren Freigabeelements in das Handgriffgehäuse hinein ermöglicht werden.It is further proposed that the machine tool comprises at least the movement-dependent unit which is provided to move the release element and the further release element in opposite directions as a result of an actuation of the release element or of the further release element. It can be advantageously in an arrangement of the release element on a side facing away from the further release element side of the handle housing as a result of actuation of the release element and the further release element, a movement of the release element and the further release element in the handle housing inside.

Vorteilhafterweise ist die Bewegungsabhängigkeitseinheit als Gelenkeinheit ausgebildet. Unter einer "Gelenkeinheit" soll hier insbesondere eine Einheit verstanden werden, die zumindest zwei Bauteile beweglich relativ zueinander, insbesondere schwenkbar und/oder drehbar relativ zueinander, miteinander verbindet, wobei eine Bewegung eines der Bauteile über eine Gelenkstelle der Einheit eine Bewegung des anderen Bauteils hervorruft. Die Gelenkstelle kann hierbei beispielsweise als Verzahnung ausgebildet sein oder eine andere, einem Fachmann als sinnvoll erscheinende Ausgestaltung aufweisen. Somit kann konstruktiv einfach eine Bewegungsabhängigkeit zwischen dem Freigabeelement und dem weiteren Freigabeelement erreicht werden, insbesondere bei einer schwenkbaren Lagerung des Freigabeelements und des weiteren Freigabeelements.Advantageously, the movement-dependence unit is designed as a joint unit. A "joint unit" is to be understood here as meaning, in particular, a unit which connects at least two components movably relative to one another, in particular pivotably and / or rotatably relative to one another, wherein a movement of one of the components causes a movement of the other component via an articulation point of the unit , The articulation point can in this case be designed, for example, as toothing or have another design which appears appropriate to a person skilled in the art. Thus, structurally simple movement dependence between the release element and the further release element can be achieved, in particular with a pivotable mounting of the release element and the further release element.

Bevorzugt ist die Bewegungsabhängigkeitseinheit als Gelenkeinheit ausgebildet, die zumindest ein Gelenkelement aufweist, das einstückig mit dem Freigabeelement oder dem weiteren Freigabeelement ausgebildet ist. Unter "einstückig" soll insbesondere zumindest stoffschlüssig verbunden verstanden werden, beispielsweise durch einen Schweißprozess, einen Klebeprozess, einen Anspritzprozess und/oder einen anderen, dem Fachmann als sinnvoll erscheinenden Prozess, und/oder vorteilhaft in einem Stück geformt verstanden werden, wie beispielsweise durch eine Herstellung aus einem Guss und/oder durch eine Herstellung in einem Ein- oder Mehrkomponentenspritzverfahren und vorteilhaft aus einem einzelnen Rohling. Es kann vorteilhaft eine kompakte Anordnung des Gelenkelements am Freigabeelement oder am weiteren Freigabeelement erreicht werden. Ferner können vorteilhaft Bauraum, Bauteile und Kosten eingespart werden.Preferably, the movement-dependent unit is designed as a joint unit which has at least one joint element which is formed integrally with the release element or the further release element. Under "one piece" should be understood in particular at least cohesively connected, for example, by a welding process, a gluing process, an injection process and / or another, the skilled person appear useful process, and / or advantageously formed in one piece, such as by a production of a cast and or by a preparation in a one-component or multi-component injection molding process and advantageously from a single blank. It can be advantageously achieved a compact arrangement of the hinge element on the release element or the further release element. Furthermore, advantageous space, components and costs can be saved.

Zudem wird vorgeschlagen, dass die Schalteinheit zumindest ein Federelement aufweist, das dazu vorgesehen ist, zumindest das Freigabeelement mit einer Federkraft in Richtung einer Verriegelungsstellung des Freigabeelements zu beaufschlagen. Unter einem "Federelement" soll insbesondere ein makroskopisches Element verstanden werden, das zumindest eine Erstreckung aufweist, die in einem normalen Betriebszustand um zumindest 10 %, insbesondere um wenigstens 20 %, vorzugsweise um mindestens 30 % und besonders vorteilhaft um zumindest 50 % elastisch veränderbar ist, und das insbesondere eine von einer Veränderung der Erstreckung abhängige und vorzugsweise zu der Veränderung proportionale Gegenkraft erzeugt, die der Veränderung entgegenwirkt. Unter einer "Erstreckung" eines Elements soll insbesondere ein maximaler Abstand zweier Punkte einer senkrechten Projektion des Elements auf eine Ebene verstanden werden. Unter einem "makroskopischen Element" soll insbesondere ein Element mit einer Erstreckung von zumindest 1 mm, insbesondere von wenigstens 5 mm und vorzugsweise von mindestens 10 mm verstanden werden. Bevorzugt wird das Federelement von einer Druckfeder gebildet. Es ist jedoch auch denkbar, dass das Federelement eine andere, einem Fachmann als sinnvoll erscheinende Ausgestaltung aufweist, wie beispielsweise eine Ausgestaltung als Zugfeder usw.. Mittels des Federelements kann vorteilhaft eine selbsttätige Bewegung des Freigabeelements in die Verriegelungsstellung erreicht werden, insbesondere nachdem ein Bediener eine Krafteinwirkung auf das Schaltklinkenelement aufgehoben hat und sich das Schaltklinkenelement in einer Ausgangsstellung des Schaltklinkenelements befindet.In addition, it is proposed that the switching unit has at least one spring element which is provided to act on at least the release element with a spring force in the direction of a locking position of the release element. A "spring element" is to be understood in particular as a macroscopic element which has at least one extension that is elastically changeable by at least 10%, in particular by at least 20%, preferably by at least 30% and particularly advantageously by at least 50% in a normal operating state , And in particular generates a dependent on a change in the extension and preferably proportional to the change counterforce, which counteracts the change. An "extension" of an element should, in particular, be understood to mean a maximum distance between two points of a vertical projection of the element onto a plane. By a "macroscopic element" is meant in particular an element with an extension of at least 1 mm, in particular of at least 5 mm and preferably of at least 10 mm. Preferably, the spring element is formed by a compression spring. However, it is also conceivable that the spring element has another, a skilled person appear appropriate design, such as a design as a tension spring, etc. By means of the spring element can advantageously be achieved an automatic movement of the release element in the locked position, in particular after an operator Force has lifted to the pawl element and the pawl element is in an initial position of the pawl element.

Vorteilhafterweise weist die Schalteinheit zumindest das Federelement auf, das sich mit einem Ende an dem Freigabeelement abstützt und mit einem weiteren Ende an einem weiteren Freigabeelement der Schalteinheit abstützt. Es ist jedoch auch denkbar, dass die Schalteinheit zumindest zwei Federelemente aufweist, wobei ein Federelement dem Freigabeelement zugeordnet ist und ein Federelement dem weiteren Freigabeelement zugeordnet ist. Mittels der erfindungsgemäßen Ausgestaltung kann konstruktiv einfach eine Rückstellfunktion des Freigabeelements und des weiteren Freigabeelements realisiert werden.Advantageously, the switching unit has at least the spring element, which is supported at one end on the release element and is supported with a further end to a further release element of the switching unit. However, it is also conceivable that the switching unit has at least two spring elements, wherein a spring element is associated with the release element and a spring element is associated with the further release element. By means of the embodiment according to the invention, a reset function of the release element and the further release element can be realized structurally simple.

Des Weiteren wird vorgeschlagen, dass das Freigabeelement zumindest eine Entriegelungsaufnahmeausnehmung aufweist, die dazu vorgesehen ist, in einer Entriegelungsstellung des Freigabeelements infolge einer Betätigung des Schaltklinkenelements ein Sperrelement der Schalteinheit aufzunehmen. Vorzugsweise greift das Sperrelement in der Entriegelungsstellung des Freigabeelements infolge einer Betätigung des Schaltklinkenelements in die Entriegelungsaufnahmeausnehmung ein, um eine Bewegung des Schaltklinkenelements zu ermöglichen. Bevorzugt schlägt das Sperrelement in einer Sperrstellung des Freigabeelements zu einer Sperrung einer Bewegung des Schaltklinkenelements infolge einer Betätigung des Schaltklinkenelements an einer Sperrfläche des Freigabeelements an. Mittels der erfindungsgemäßen Ausgestaltung kann konstruktiv einfach eine Entriegelung der Bewegungssperre erreicht werden. Zudem kann konstruktiv einfach eine Sperrung einer Bewegung des Schaltklinkenelements in der Sperrstellung ermöglicht werden, indem eine Aufnahme des Sperrelements in der Entriegelungsaufnahmeausnehmung in der Sperrstellung des Freigabeelements verhindert wird.Furthermore, it is proposed that the release element has at least one Entriegelungsaufnahmeausnehmung which is intended to receive in a unlocked position of the release element as a result of actuation of the pawl element, a blocking element of the switching unit. Preferably, in the unlocked position of the release member, as a result of actuation of the pawl member, the locking member engages the unlock receiving recess to permit movement of the pawl member. In a blocking position of the release element, the blocking element preferably acts to block a movement of the pawl element as a result of an actuation of the pawl element on a blocking surface of the release element. By means of the design according to the invention can be achieved structurally simple unlocking the movement lock. In addition, structurally simple blocking of a movement of the pawl element in the blocking position can be made possible by a recording of the locking element is prevented in the Entriegelungsaufnahmeausnehmung in the locked position of the release element.

Ferner wird vorgeschlagen, dass die erfindungsgemäße Werkzeugmaschine zumindest das Handgriffgehäuse umfasst, wobei der Betätigungsbereich des Freigabeelements nach einer Betätigung zumindest im Wesentlichen bündig mit einer Außenfläche des Handgriffgehäuses abschließt. Unter "zumindest im Wesentlichen bündig abschließen" soll hier insbesondere eine Anordnung des Betätigungsbereichs nach einer Betätigung des Freigabeelements, insbesondere nach einem Einschwenken des Freigabeelements in das Handgriffgehäuse, verstanden werden, wobei sich der Betätigungsbereich ausgehend von einem vom Handgriffgehäuse umschlossenen Raum in Richtung der Außenfläche des Handgriffgehäuses, entlang einer zumindest im Wesentlichen senkrecht zur Außenfläche des Handgriffgehäuses verlaufenden Richtung betrachtet, maximal 2 mm über die Außenfläche erstreckt und sich besonders bevorzugt maximal bis zur Außenfläche des Handgriffgehäuses erstreckt. Somit erstreckt sich der Betätigungsbereich des Freigabeelements nach einer Betätigung nicht über die Außenfläche des Handgriffgehäuses hinaus. Es kann vorteilhaft infolge eines vollständigen Eintauchens des Freigabeelements in das Handgriffgehäuse eine kompakte Anordnung des Freigabeelements in einem betätigten Zustand erreicht werden. Ferner kann einem Bediener vorteilhaft optisch signalisiert werden, dass das Freigabeelement sich in einer Entriegelungsstellung befindet.It is also proposed that the machine tool according to the invention comprises at least the handle housing, wherein the actuation region of the release element terminates at least substantially flush with an outer surface of the handle housing after actuation. The term "at least substantially flush" should in particular be understood to mean an arrangement of the actuating region after an actuation of the release element, in particular after the release element has pivoted into the handle housing, the actuating region starting from a space enclosed by the handle housing in the direction of the outer surface of the handle Handle housing, viewed along a direction extending at least substantially perpendicular to the outer surface of the handle housing direction, a maximum of 2 mm extends over the outer surface and more preferably extends maximally to the outer surface of the handle housing. Thus, the actuating portion of the release member does not extend beyond the outer surface of the handle housing after actuation. It can be achieved advantageously in an actuated state as a result of a complete immersion of the release element in the handle housing, a compact arrangement of the release element. Furthermore, an operator can advantageously be optically signaled that the release element is in an unlocked position.

Besonders bevorzugt umfasst die erfindungsgemäße Werkzeugmaschine zumindest das Handgriffgehäuse, wobei der Betätigungsbereich des Freigabeelements und ein Betätigungsbereich eines weiteren Freigabeelements der Schalteinheit nach einer Betätigung zumindest im Wesentlichen bündig mit einer Außenfläche des Handgriffgehäuses abschließen. Somit kann vorteilhaft ein vollständiges Eintauchen des Betätigungsbereichs des Freigabeelements und des Betätigungsbereichs des weiteren Freigabeelements in einem betätigten Zustand des Freigabeelements und/oder des weiteren Freigabeelements erreicht werden.Particularly preferably, the machine tool according to the invention comprises at least the handle housing, the actuating region of the release element and an actuating region of a further release element of the switching unit terminate at least substantially flush with an outer surface of the handle housing after actuation. Thus, a complete immersion of the actuation region of the release element and of the actuation region of the further release element in an actuated state of the release element and / or the further release element can advantageously be achieved.

Des Weiteren wird vorgeschlagen, dass das Schaltklinkenelement schwenkbar, insbesondere schwenkbar relativ zum Handgriffgehäuse, um eine als Schwenkachse ausgebildete Bewegungsachse des Schaltklinkenelements gelagert ist. Es ist jedoch auch denkbar, dass das Schaltklinkenelement translatorisch beweglich entlang einer als Translationsachse ausgebildeten Bewegungsachse des Schaltklinkenelements gelagert ist. Besonders bevorzugt verläuft die Schwenkachse zumindest im Wesentlichen senkrecht zur Verbindungsebene des Handgriffgehäuses. Es kann vorteilhaft ein einfach zu bedienendes Schaltklinkenelement geschaffen werden, bei dem eine Lagerung unempfindlich gegenüber einer Verschmutzung ist. Zudem kann vorteilhaft eine Hebelwirkung zu einer komfortablen Betätigung des Schaltelements mittels des Schaltklinkenelements genutzt werden.Furthermore, it is proposed that the pawl element is pivotable, in particular pivotable relative to the handle housing, mounted about a movement axis of the pawl element formed as a pivot axis. However, it is also conceivable that the pawl element is mounted translationally movable along a movement axis of the pawl element designed as a translation axis. Particularly preferably, the pivot axis extends at least substantially perpendicular to the connection plane of the handle housing. It can be advantageous to create an easy-to-use pawl element, in which a storage is insensitive to contamination. In addition, a lever effect can advantageously be used for a comfortable actuation of the switching element by means of the pawl element.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Figur 1 zeigt eine Werkzeugmaschine 10a, die von einer als Winkelschleifmaschine 12a ausgebildeten tragbaren Werkzeugmaschine 10a gebildet wird. Die tragbare Werkzeugmaschine 10a umfasst zumindest eine Schalteinheit 14a, die zumindest ein beweglich gelagertes Schaltklinkenelement 16a zu einer Betätigung eines Schaltelements 50a der Schalteinheit 14a (Figur 3) und zumindest ein Freigabeelement 18a zu einer Entriegelung einer Bewegungssperre des Schaltklinkenelements 16a aufweist. Hierbei weist die tragbare Werkzeugmaschine 10a zumindest eine Werkzeugmaschinenschaltvorrichtung auf, die zumindest die Schalteinheit 14a und zumindest eine Lagereinheit 90a zu einer beweglichen Lagerung des Schaltklinkenelements 16a der Schalteinheit 14a umfasst. Das Freigabeelement 18a umfasst zumindest einen Betätigungsbereich 20a, der zumindest teilweise seitlich neben einer Bedienfläche 22a des Schaltklinkenelements 16a angeordnet ist. Das Freigabeelement 18a ist hierbei an einem Handgriffgehäuse 32a der tragbaren Werkzeugmaschine 10a angeordnet. Das Handgriffgehäuse 32a umfasst einen stielförmigen Griffbereich 52a, an dem das Schaltklinkenelement 16a angeordnet ist. Der stielförmige Griffbereich 52a des Handgriffgehäuses 32a bildet einen Haupthandgriff der tragbaren Werkzeugmaschine 10a. Hierbei erstreckt sich der von dem stielförmigen Griffbereich 52a gebildete Haupthandgriff zumindest im Wesentlichen ausgehend von einem Anbindungsbereich 54a des Handgriffgehäuses 32a in eine vom Anbindungsbereich 54a abgewandte Richtung bis zu einer Seite 56a des Handgriffgehäuses 32a, an der ein Kabel der als Winkelschleifmaschine 12a ausgebildeten tragbaren Werkzeugmaschine 10a zur Energieversorgung angeordnet ist. Der stielförmige Griffbereich 52a des Handgriffgehäuses 32a ist um einen Winkel kleiner als 30° relativ zu einer Haupterstreckungsrichtung 58a des Handgriffgehäuses 32a bzw. zu einer Haupterstreckungsrichtung 60a der tragbaren Werkzeugmaschine 10a geneigt angeordnet. FIG. 1 shows a machine tool 10a, which is formed by a designed as an angle grinder 12a portable power tool 10a. The portable power tool 10a comprises at least one switching unit 14a, which has at least one movably mounted pawl element 16a for actuating a switching element 50a of the switching unit 14a (FIG. FIG. 3 ) and at least one release element 18a for unlocking a movement lock of the pawl element 16a. In this case, the portable power tool 10a has at least one machine tool switching device which comprises at least the switching unit 14a and at least one bearing unit 90a for a movable mounting of the switching pawl element 16a of the switching unit 14a. The release element 18a comprises at least one actuating region 20a, which is arranged at least partially laterally next to a control surface 22a of the pawl element 16a. The release element 18a is in this case arranged on a handle housing 32a of the portable power tool 10a. The handle housing 32a includes a handle-shaped handle portion 52a on which the pawl member 16a is disposed. The handle-shaped handle portion 52a of the handle housing 32a constitutes a main handle of the portable power tool 10a. Here, the main handle formed by the handle-shaped handle portion 52a at least substantially extends from a connection portion 54a of the handle housing 32a in a direction away from the connection portion 54a direction to a side 56a of the handle housing 32a, on which a cable designed as an angle grinder 12a portable power tool 10a arranged for power supply. The handle-shaped handle portion 52a of the handle case 32a is inclined at an angle smaller than 30 ° relative to a main extension direction 58a of the handle case 32a and a main extension direction 60a of the portable power tool 10a, respectively.

Die als Winkelschleifmaschine 12a ausgebildete tragbare Werkzeugmaschine 10a umfasst ferner eine Schutzhaubeneinheit 62a, ein Antriebsgehäuse 64a und ein Abtriebsgehäuse 66a. Aus dem Abtriebsgehäuse 66a heraus erstreckt sich eine als Spindel (hier nicht näher dargestellt) ausgebildete Ausgangswelle einer Abtriebseinheit 68a der tragbaren Werkzeugmaschine 10a, an der ein Bearbeitungswerkzeug 70a zu einer Bearbeitung eines Werkstücks (hier nicht näher dargestellt) fixiert werden kann. Das Bearbeitungswerkzeug 70a ist als Schleifscheibe ausgebildet. Es ist jedoch auch denkbar, dass das Bearbeitungswerkzeug 70a als Trenn- oder Polierscheibe ausgebildet ist. Die tragbare Werkzeugmaschine 10a umfasst das Antriebsgehäuse 64a zur Aufnahme einer Antriebseinheit 72a der tragbaren Werkzeugmaschine 10a und das Abtriebsgehäuse 66a zu einer Aufnahme der Abtriebseinheit 68a. Die Antriebseinheit 72 ist dazu vorgesehen, das Bearbeitungswerkzeug 70a über die Abtriebseinheit 68a rotierend anzutreiben. Das Bearbeitungswerkzeug 70a kann hierbei mittels eines Befestigungselements (hier nicht näher dargestellt) zur Bearbeitung eines Werkstücks drehfest mit der Spindel verbunden werden. Somit kann das Bearbeitungswerkzeug 70a in einem Betrieb der tragbaren Werkzeugmaschine 10a rotierend angetrieben werden. Die Abtriebseinheit 68a ist über ein als Ritzel ausgebildetes und rotierend antreibbares Antriebselement (hier nicht näher dargestellt) der Antriebseinheit 72a auf eine, einem Fachmann bereits bekannte Art und Weise mit der Antriebseinheit 72a verbunden. Zudem ist an dem Abtriebsgehäuse 66a ein Zusatzhandgriff 74a angeordnet. Der Zusatzhandgriff 74a erstreckt sich in einem am Abtriebsgehäuse 66a montierten Zustand quer zur Haupterstreckungsrichtung 60a der tragbaren Werkzeugmaschine 10a.The portable power tool 10a designed as an angle grinder 12a further comprises a protective hood unit 62a, a drive housing 64a and a driven housing 66a. Extending out of the output housing 66a is a spindle (not shown here in detail) of an output shaft of an output unit 68a of the portable power tool 10a, on which a machining tool 70a for machining a workpiece (not shown here) can be fixed. The machining tool 70a is designed as a grinding wheel. However, it is also conceivable that the machining tool 70a is formed as a separating or polishing wheel. The portable power tool 10a includes the drive housing 64a for receiving a drive unit 72a of the portable power tool 10a and the output housing 66a for receiving the output unit 68a. The drive unit 72 is provided to rotate the machining tool 70a via the output unit 68a. The machining tool 70a can in this case by means of a fastener (not shown here) for machining a workpiece rotatably connected to the spindle. Thus, the machining tool 70a can be rotationally driven in an operation of the portable power tool 10a. The output unit 68a is connected to the drive unit 72a in a manner already known to a person skilled in the art by means of a drive element (not shown here in detail) designed as a pinion and rotationally drivable. In addition, an auxiliary handle 74a is arranged on the output housing 66a. The auxiliary handle 74a extends in a state mounted on the output housing 66a transversely to the main direction of extent 60a of the portable power tool 10a.

Figur 2 zeigt eine Detailansicht des am Handgriffgehäuse 32a angeordneten Freigabeelements 18a der Schalteinheit 14a in einem unbetätigten Zustand des Freigabeelements 18a. Das Freigabeelement 18a ist in einem Bereich eines dem Anbindungsbereich 54a zugewandten Endes des Handgriffgehäuses 32a am Handgriffgehäuse 32a angeordnet. Zudem ist das Freigabeelement 18a zumindest teilweise außerhalb des stielförmigen Griffbereichs 52a angeordnet. Hierbei ist zumindest der Betätigungsbereich 20a des Freigabeelements 18a größtenteils außerhalb des stielförmigen Griffbereichs 52a angeordnet. Das Freigabeelement 18a ist schwenkbar um zumindest eine Freigabebewegungsachse 24a gelagert. Die Freigabebewegungsachse 24a ist somit als Freigabeschwenkachse ausgebildet. Das Freigabeelement 18a weist zumindest die Freigabebewegungsachse 24a auf, die in einer sich zumindest im Wesentlichen senkrecht zu einer Bewegungsachse 26a des Schaltklinkenelements 16a erstreckenden Ebene verläuft. Das Schaltklinkenelement 16a ist hierbei schwenkbar um die als Schwenkachse 48a ausgebildete Bewegungsachse 26a des Schaltklinkenelements 16a gelagert. Die als Schwenkachse 48a ausgebildete Bewegungsachse 26a verläuft zumindest im Wesentlichen senkrecht zu einer Verbindungsebene des Handgriffgehäuses 32a, in der zwei Handgriffgehäuseschalenelemente 76a, 78a des Handgriffgehäuses 32a miteinander verbunden sind. Somit verläuft die Freigabebewegungsachse 24a zumindest im Wesentlichen parallel zur Verbindungsebene des Handgriffgehäuses 32a. Ferner verläuft die Freigabebewegungsachse 24a zumindest im Wesentlichen quer zu der als Schwenkachse 48a ausgebildeten Bewegungsachse 26a des Schaltklinkenelements 16a. FIG. 2 shows a detailed view of the arranged on the handle housing 32a release member 18a of the switching unit 14a in an unactuated state of the release member 18a. The release element 18a is arranged on the handle housing 32a in a region of an end of the handle housing 32a facing the connection region 54a. In addition, the release element 18a is at least partially disposed outside of the handle-shaped handle portion 52a. In this case, at least the actuating region 20a of the release element 18a is for the most part arranged outside the handle-shaped grip region 52a. The release element 18a is pivotally mounted about at least one release movement axis 24a. The release movement axis 24a is thus designed as a release pivot axis. The release element 18a has at least the release movement axis 24a, which extends in a plane extending at least substantially perpendicular to a movement axis 26a of the pawl element 16a. The pawl element 16a is in this case pivotally mounted about the movement axis 26a of the pawl element 16a designed as a pivot axis 48a. The movement axis 26a formed as a pivot axis 48a extends at least substantially perpendicular to a connection plane of the handle housing 32a, in which two handle housing shell elements 76a, 78a of the handle housing 32a are connected to one another. Thus, the release movement axis 24a extends at least substantially parallel to the connection plane of the handle housing 32a. Furthermore, the release movement axis 24a runs at least substantially transversely to the movement axis 26a of the pawl element 16a, which is designed as a pivot axis 48a.

Des Weiteren weist die Schalteinheit 14a zumindest ein weiteres Freigabeelement 28a auf. Das weitere Freigabeelement 28a ist ebenfalls im Bereich des dem Anbindungsbereich 54a zugewandten Endes des Handgriffgehäuses 32a am Handgriffgehäuse 32a angeordnet (Figuren 2 und 3). Zudem ist das weitere Freigabeelement 28a ebenfalls zumindest teilweise außerhalb des stielförmigen Griffbereichs 52a angeordnet. Hierbei ist zumindest ein Betätigungsbereich 34a des weiteren Freigabeelements 28a größtenteils außerhalb des stielförmigen Griffbereichs 52a angeordnet. Das weitere Freigabeelement 28a ist spiegelsymmetrisch zum Freigabeelement 18a angeordnet. Somit weist das weitere Freigabeelement 28a zumindest den Betätigungsbereich 34a auf, der, bezogen auf eine sich zumindest im Wesentlichen senkrecht zur Bewegungsachse 26a des Schaltklinkenelements 16a erstreckende Ebene, spiegelsymmetrisch zum Betätigungsbereich 20a des Freigabeelements18a zumindest teilweise seitlich neben der Bedienfläche 22a des Schaltklinkenelements 16a angeordnet ist. Das weitere Freigabeelement 28a ist schwenkbar um zumindest eine weitere Freigabebewegungsachse 80a gelagert. Die weitere Freigabebewegungsachse 80a ist als Freigabeschwenkachse ausgebildet. Die weitere Freigabebewegungsachse 80a verläuft hierbei in einer sich zumindest im Wesentlichen senkrecht zu der als Schwenkachse 48a ausgebildeten Bewegungsachse 26a des Schaltklinkenelements 16a erstreckenden Ebene. Somit verläuft die weitere Freigabebewegungsachse 80a zumindest im Wesentlichen parallel zur Verbindungsebene des Handgriffgehäuses 32a. Ferner verläuft die weitere Freigabebewegungsachse 80a zumindest im Wesentlichen quer zu der als Schwenkachse 48a ausgebildeten Bewegungsachse 26a des Schaltklinkenelements 16a. Die weitere Freigabebewegungsachse 80a verläuft zumindest im Wesentlichen parallel zur Freigabebewegungsachse 24a des Freigabeelements 18a. Das Freigabeelement 18a und das weitere Freigabeelement 28a sind relativ beweglich zueinander gelagert.Furthermore, the switching unit 14a has at least one further release element 28a. The further release element 28a is likewise arranged on the handle housing 32a in the region of the end of the handle housing 32a facing the connection region 54a ( FIGS. 2 and 3 ). In addition, the further release element 28a is likewise arranged at least partially outside the handle-shaped grip region 52a. In this case, at least one actuating region 34a of the further release element 28a is for the most part arranged outside the handle-shaped grip region 52a. The further release element 28a is arranged mirror-symmetrically to the release element 18a. Thus, the further release element 28a at least the actuating portion 34a, which, relative to an at least substantially perpendicular to the movement axis 26a of the pawl member 16a extending plane mirror-symmetrical to the actuating portion 20a of the release member 18a at least partially disposed laterally next to the control surface 22a of the pawl member 16a. The further release element 28a is pivotally mounted about at least one further release movement axis 80a. The further release movement axis 80a is designed as a release pivot axis. The further release movement axis 80a in this case extends in a plane extending at least substantially perpendicular to the movement axis 26a of the pawl element 16a designed as a pivot axis 48a. Thus, the further release movement axis 80a extends at least substantially parallel to the connection plane of the handle housing 32a. Furthermore, the further release movement axis 80a extends at least substantially transversely to the movement axis 26a of the pawl element 16a, which is designed as a pivot axis 48a. The further release movement axis 80a runs at least substantially parallel to the release movement axis 24a of the release element 18a. The release member 18a and the further release member 28a are mounted relatively movable to each other.

Ferner weist die tragbare Werkzeugmaschine 10a zumindest eine Bewegungsabhängigkeitseinheit 30a auf, die das Freigabeelement 18a und das weitere Freigabeelement 28a zumindest in einem montierten Zustand bewegungstechnisch miteinander koppelt (Figur 4). Die Bewegungsabhängigkeitseinheit 30a, ist dazu vorgesehen, infolge einer Betätigung des Freigabeelements 18a oder des weiteren Freigabeelements 28a das Freigabeelement 18a und das weitere Freigabeelement 28a in entgegengesetzt gerichtete Richtungen zu bewegen. Somit werden das Freigabeelement 18a und das weitere Freigabeelement 28a mittels der Bewegungsabhängigkeitseinheit 30a infolge einer Betätigung des Freigabeelements 18a oder des weiteren Freigabeelements 28a stets gemeinsam bewegt. Hierbei werden das Freigabeelement 18a und das weitere Freigabeelement 28a infolge einer Betätigung des Freigabeelements 18a oder des weiteren Freigabeelements 28a in eine dem Handgriffgehäuse 32a zugewandte Richtung mittels der Bewegungsabhängigkeitseinheit 30a in eine dem Handgriffgehäuse 32a zugewandte Richtung bewegt. Die Bewegungsabhängigkeitseinheit 30a ist als Gelenkeinheit 36a ausgebildet. Die als Gelenkeinheit 36a ausgebildete Bewegungsabhängigkeitseinheit 30a weist zumindest ein Gelenkelement 38a auf, das einstückig mit dem Freigabeelement 18a oder dem weiteren Freigabeelement 28a ausgebildet ist. Das Gelenkelement 38a ist hierbei einstückig mit dem Freigabeelement 18a ausgebildet (Figuren 4 und 8). Ferner weist die als Gelenkeinheit 36a ausgebildete Bewegungsabhängigkeitseinheit 30a ein weiteres Gelenkelement 40a auf, das einstückig mit dem weiteren Freigabeelement 28a ausgebildet ist. Das Gelenkelement 38a und das weitere Gelenkelement 40a sind dazu vorgesehen, mittels eines Zusammenwirkens das Freigabeelement 18a und das weitere Freigabeelement 28a abhängig voneinander zu bewegen. Das weitere Gelenkelement 40a umfasst eine Eingriffausnehmung 82a, die eine zumindest im Wesentlichen U-förmige Ausgestaltung aufweist. Das Gelenkelement 38a greift hierbei in einem montierten Zustand in die Eingriffausnehmung 82a ein. Das Gelenkelement 38a weist hierbei eine tropfenförmige Ausgestaltung auf, dessen kreisscheibenförmiger Teilbereich in einem montierten Zustand des Freigabeelements 18a und des weiteren Freigabeelements 28a in der Eingriffausnehmung 82a angeordnet ist.Furthermore, the portable power tool 10a has at least one movement-dependent unit 30a, which couples the release element 18a and the further release element 28a, at least in an assembled state, to one another in terms of movement ( FIG. 4 ). The movement dependency unit 30a is provided to move the release member 18a and the further release member 28a in opposite directions as a result of an operation of the release member 18a or the further release member 28a. Thus, the release member 18a and the further release member 28a by means of the movement-dependent unit 30a always moves together due to an actuation of the release member 18a or the further release member 28a. In this case, the release element 18a and the further release element 28a are moved in a direction facing the handle housing 32a by means of the movement-dependent unit 30a in a direction facing the handle housing 32a, as a result of actuation of the release element 18a or the further release element 28a. The movement dependency unit 30a is formed as a hinge unit 36a. The movement-dependent unit 30a designed as a joint unit 36a has at least one joint element 38a, which is formed integrally with the release element 18a or the further release element 28a. The joint element 38a is in this case formed integrally with the release element 18a ( FIGS. 4 and 8th ). Furthermore, the movement-dependent unit 30a designed as a joint unit 36a has a further joint element 40a, which is formed integrally with the further release element 28a. The joint element 38a and the further joint element 40a are provided to move the release element 18a and the further release element 28a depending on each other by means of an interaction. The further joint element 40a comprises an engagement recess 82a, which has an at least substantially U-shaped configuration. In this case, the joint element 38a engages in the engagement recess 82a in an assembled state. The joint element 38a in this case has a teardrop-shaped configuration, the circular disk-shaped portion is arranged in an assembled state of the release element 18a and the further release element 28a in the engagement recess 82a.

Infolge einer Betätigung des Freigabeelements 18a oder des weiteren Freigabeelements 28a werden Kräfte mittels eines Zusammenwirkens des Gelenkelements 38a und des weiteren Gelenkelements 40a über Flankenbereiche des Gelenkelements 38a und des weiteren Gelenkelements 40a zwischen dem Freigabeelement 18a und dem weiteren Freigabeelement 28a übertragen, die eine voneinander abhängige Bewegung des Freigabeelements 18a und des weiteren Freigabeelements 28a hervorrufen. Die Flankenbereiche des weiteren Gelenkelements 40a werden hierbei von abgewinkelten Schenkelbereichen der Eingriffausnehmung 82a gebildet. Die Flankenbereiche des Gelenkelements 38a werden von Seitenwänden des Gelenkelements 38a gebildet. Eine Ausgestaltung der Bewegungsabhängigkeitseinheit 30a als Verzahnungsbewegungsabhängigkeitseinheit ist ebenfalls denkbar, wobei Kräfte zu einer abhängigen Bewegung des Freigabeelements 18a und des weiteren Freigabeelements 28a über Zahnflanken von Zähnen einer Verzahnung der Verzahnungsbewegungsabhängigkeitseinheit übertragen werden können. Hierbei ist jeweils ein Verzahnungselement einstückig mit dem Freigabeelement 18a und mit dem weiteren Freigabeelement 28a ausgebildet.As a result of an actuation of the release member 18a or the further release member 28a forces are transmitted by means of an interaction of the joint member 38a and the other joint member 40a on flank portions of the joint member 38a and the other joint member 40a between the release member 18a and the other release member 28a, which is a mutually dependent movement of the release member 18a and the further release member 28a cause. The flank regions of the further joint element 40a are in this case formed by angled leg regions of the engagement recess 82a. The flank portions of the hinge member 38a are formed by side walls of the hinge member 38a. An embodiment of the movement dependency unit 30a as a gear movement dependency unit is also conceivable, wherein forces can be transmitted to a dependent movement of the release element 18a and the further release element 28a via tooth flanks of teeth of a toothing of the Verzahnungsbewegungsabhängigkeitseinheit. In this case, a toothed element is formed in one piece with the release element 18a and with the further release element 28a.

Des Weiteren weist die Schalteinheit 14a zumindest ein Federelement 42a auf, das dazu vorgesehen ist, zumindest das Freigabeelement 18a mit einer Federkraft in Richtung einer Verriegelungsstellung des Freigabeelements 18a zu beaufschlagen (Figur 8). Das Federelement 42a ist als Druckfeder ausgebildet. Hierbei stützt sich das Federelement 42a mit einem Ende an dem Freigabeelement 18a ab und mit einem weiteren Ende stützt sich das Federelement 42a an dem weiteren Freigabeelement 28a der Schalteinheit 14a ab. Das Freigabeelement 18a und das weitere Freigabeelement 28a umfassen jeweils eine Federaufnahmeausnehmung 84a, 86a, in der das Federelement 42a in einem montierten Zustand angeordnet ist. Die Federaufnahmeausnehmungen 84a, 86a sind als halbzylinderförmige Aufnahmemulden ausgebildet. Es ist jedoch auch denkbar, dass die Federaufnahmeausnehmungen 84a, 86a eine andere, einem Fachmann als sinnvoll erscheinende Ausgestaltung aufweisen.Furthermore, the switching unit 14a has at least one spring element 42a, which is provided to apply at least the release element 18a with a spring force in the direction of a locking position of the release element 18a ( FIG. 8 ). The spring element 42a is designed as a compression spring. In this case, the spring element 42a is supported with one end on the release element 18a and with a further end, the spring element 42a is supported on the further release element 28a of the switching unit 14a. The release member 18a and the further release member 28a each include a spring receiving recess 84a, 86a in which the spring member 42a is disposed in an assembled state. The spring receiving recesses 84a, 86a are formed as semi-cylindrical receiving troughs. However, it is also conceivable that the spring receiving recesses 84a, 86a have another, to those skilled appear appropriate design.

Ferner weist das Freigabeelement 18a zumindest eine Entriegelungsaufnahmeausnehmung 44a auf, die dazu vorgesehen ist, in einer Entriegelungsstellung des Freigabeelements 18a infolge einer Betätigung des Schaltklinkenelements 16a ein Sperrelement 94a der Schalteinheit 14a aufzunehmen (Figur 6). Das Sperrelement 94a ist an einem Hebellagerelement 88a der Lagereinheit 90a der tragbaren Werkzeugmaschine 10a angeordnet. Hierbei ist das Sperrelement 94a einstückig mit dem Hebellagerelement 88a ausgebildet. Das weitere Freigabeelement 28a umfasst ebenfalls zumindest eine Entriegelungsaufnahmeausnehmung 92a, die dazu vorgesehen ist, in einer Entriegelungsstellung des weiteren Freigabeelements 28a infolge einer Betätigung des Schaltklinkenelements 16a ein weiteres Sperrelement 106a der Schalteinheit 14a aufzunehmen (Figur 7). Das weitere Sperrelement 106a ist ebenfalls an dem Hebellagerelement 88a angeordnet. Hierbei ist das weitere Sperrelement 106a ebenfalls einstückig mit dem Hebellagerelement 88a ausgebildet. Das Sperrelement 94a schlägt in einer Verriegelungsstellung des Freigabeelements 18a, in der eine Bewegung des Schaltklinkenelements 16a weitestgehend mittels der Bewegungssperre verhindert wird, infolge einer Betätigung des Schaltklinkenelements 16a an einer Sperrfläche 96a des Freigabeelements 18a an. Die Sperrfläche 96a ist an einer dem Schaltklinkenelement 16a zugewandten Seite des Freigabeelements 18a angeordnet. Hierbei ist die Sperrfläche 96a seitlich neben der Entriegelungsaufnahmeausnehmung 44a des Freigabeelements 18a angeordnet (Figur 8). Ferner schlägt das weitere Sperrelement 106a in einer Verriegelungsstellung des weiteren Freigabeelements 28a, in der eine Bewegung des Schaltklinkenelements 16a weitestgehend mittels der Bewegungssperre verhindert wird, infolge einer Betätigung des Schaltklinkenelements 16a an einer weiteren Sperrfläche 98a des weiteren Freigabeelements 28a an. Die weitere Sperrfläche 98a ist an einer dem Schaltklinkenelement 16a zugewandten Seite des weiteren Freigabeelements 28a angeordnet. Hierbei ist die weitere Sperrfläche 98a seitlich neben der Entriegelungsaufnahmeausnehmung 92a des weiteren Freigabeelements 28a angeordnet (Figur 8).Furthermore, the release element 18a has at least one unlocking receiving recess 44a, which is provided to receive a blocking element 94a of the switching unit 14a in an unlocking position of the release element 18a as a result of an actuation of the pawl element 16a ( FIG. 6 ). The blocking element 94a is arranged on a lever bearing element 88a of the bearing unit 90a of the portable power tool 10a. Here, the blocking element 94a is formed integrally with the lever bearing element 88a. The further release element 28a likewise comprises at least one unlocking receiving recess 92a which is provided to receive a further blocking element 106a of the switching unit 14a in an unlocking position of the further release element 28a as a result of an actuation of the pawl element 16a ( FIG. 7 ). The further blocking element 106a is likewise arranged on the lever bearing element 88a. Here, the further blocking element 106a is also formed integrally with the lever bearing element 88a. The blocking element 94a strikes in a locking position of the release element 18a, in which a movement of the pawl member 16a is largely prevented by means of the movement lock, due to an actuation of the pawl member 16a on a locking surface 96a of the release member 18a. The blocking surface 96a is arranged on a side of the release element 18a facing the pawl element 16a. In this case, the blocking surface 96a is arranged laterally next to the unlocking receiving recess 44a of the release element 18a ( FIG. 8 ). Furthermore, in a locking position of the further release element 28a, in which a movement of the pawl element 16a is prevented as far as possible by means of the movement lock, the further blocking element 106a strikes a further blocking surface 98a of the further release element 28a as a result of an actuation of the pawl element 16a. The further blocking surface 98a is arranged on a side of the further release element 28a facing the pawl element 16a. In this case, the further blocking surface 98a is arranged laterally next to the unlocking receiving recess 92a of the further release element 28a ( FIG. 8 ).

Der Betätigungsbereich 20a des Freigabeelements 18a und der Betätigungsbereich 34a des weiteren Freigabeelements 28a erstrecken sich in einem unbetätigten Zustand des Freigabeelements 18a und des weiteren Freigabeelements 28a, entlang einer zumindest im Wesentlichen senkrecht zu einer Außenfläche 46a des Handgriffgehäuses 32a verlaufenden Richtung betrachtet, um mehr als 2 mm über die Außenfläche 46a hinaus. Der Betätigungsbereich 20a des Freigabeelements 18a schließt nach einer Betätigung zumindest im Wesentlichen bündig mit der Außenfläche 46a des Handgriffgehäuses 32a ab (Figur 5). Der Betätigungsbereich 34a des weiteren Freigabeelements 28a der Schalteinheit 14a schließt nach einer Betätigung ebenfalls zumindest im Wesentlichen bündig mit der Außenfläche 46a des Handgriffgehäuses 32a ab. Das Freigabeelement 18a und das weitere Freigabeelement 28a sind, entlang einer Hauptbewegungsrichtung des Schaltklinkenelements 16a betrachtet, auf einem dem Schaltklinkenelement 16a abgewandten Bereich des Handgriffgehäuses 32a angeordnet. Hierdurch kann ein Bediener den Betätigungsbereich 20a des Freigabeelements 18a oder den Betätigungsbereich 34a des weiteren Freigabeelements 28a mittels eines Zeigefingers oder mittels eines Daumens einer Hand des Bediener betätigen. Somit sind das Freigabeelement 18a und das weitere Freigabeelement 28a, entlang der Hauptbewegungsrichtung des Schaltklinkenelements 16a in Richtung des Handgriffgehäuses 32a betrachtet, oberhalb des Schaltklinkenelements 16a bzw. nach dem Schaltklinkenelement 16a angeordnet. In einer in Figur 9 dargestellten, alternativen Anordnung des Freigabeelements 18a' und des weiteren Freigabeelements 28a' sind das Freigabeelement 18a' und das weitere Freigabeelement 28a', entlang der Hauptbewegungsrichtung des Schaltklinkenelements 16a' ausgehend von dem Schaltklinkenelement 16a' in eine vom Handgriffgehäuse 32a' abgewandte Richtung betrachtet, unterhalb des Schaltklinkenelements 16a' bzw. nach dem Schaltklinkenelement 16a' angeordnet.The actuation region 20a of the release element 18a and the actuation region 34a of the further release element 28a extend in an unactuated state of the release element 18a and the further release element 28a, viewed along an at least substantially perpendicular to an outer surface 46a of the handle housing 32a direction, by more than 2 mm beyond the outer surface 46a. The actuation region 20a of the release element 18a terminates after actuation at least substantially flush with the outer surface 46a of the handle housing 32a (FIG. FIG. 5 ). The actuation region 34a of the further release element 28a of the switching unit 14a likewise ends, after an actuation, at least substantially flush with the outer surface 46a of the handle housing 32a. The release element 18a and the further release element 28a, viewed along a main movement direction of the pawl element 16a, are arranged on a region of the handle housing 32a facing away from the pawl element 16a. Thereby, an operator can operate the operating portion 20a of the releasing member 18a or the operating portion 34a of the further releasing member 28a by means of a forefinger or by means of a thumb of a hand of the operator. Thus, the release member 18a and the further release member 28a, viewed along the main direction of movement of the pawl member 16a in the direction of the handle housing 32a, above the Switching pawl element 16a and arranged after the pawl element 16a. In an in FIG. 9 1, the release element 18a 'and the further release element 28a', viewed along the main movement direction of the pawl element 16a 'starting from the pawl element 16a' in a direction away from the handle housing 32a ', are below of the pawl member 16a 'and after the pawl member 16a', respectively.

Des Weiteren weist die tragbare Werkzeugmaschine 10a zumindest die Lagereinheit 90a auf, die dazu vorgesehen ist, das Schaltklinkenelement 16a zumindest beweglich relativ zum Handgriffgehäuse 32a zu lagern. Die Lagereinheit 90a ist infolge einer Betätigung des Schaltklinkenelements 16a dazu vorgesehen, ausgehend von einem dem Anbindungsbereich 54a des Handgriffgehäuses 32a zugewandten Ende des Schaltklinkenelements 16a in Richtung eines weiteren, dem Anbindungsbereich 54a abgewandten, greifbaren Endes des Schaltklinkenelements 16a, stets eine Hubbewegung des Schaltklinkenelements 16a entlang einer Strecke mit einem Wert größer als Null zu gewährleisten. Die Lagereinheit 90a weist zumindest das Hebellagerelement 88a auf, das dazu vorgesehen ist, in Abhängigkeit einer Bewegung des Schaltklinkenelements 16a ein Schaltstößelelement 102a des Schaltelements 50a der Schalteinheit 14a zu betätigen (Figuren 3, 4 und 5). Das Hebellagerelement 88a ist an dem dem Anbindungsbereich 54a des Handgriffgehäuses 32a zugewandten Ende des Schaltklinkenelements 16a beweglich mit dem Schaltklinkenelement 16a verbunden. Ferner weist die Lagereinheit 90a zumindest ein weiteres Hebellagerelement 100a auf, das beweglich an dem Schaltklinkenelement 16a und beweglich an einem der Handgriffgehäuseschalenelemente 76a, 78a des Handgriffgehäuses 32a angeordnet ist. Das Hebellagerelement 88a und das weitere Hebellagerelement 100a sind zumindest im Wesentlichen parallel zueinander ausgerichtet. Infolge der zumindest im Wesentlichen parallelen Anordnung des Hebellagerelements 88a und des weiteren Hebellagerelements 100a wird eine Parallelführung des Schaltklinkenelements 16a infolge einer Betätigung des Schaltklinkenelements 16a realisiert. Das weitere, dem Anbindungsbereich 54a abgewandte, greifbare Ende des Schaltklinkenelements 16a ist hierbei entkoppelt von einer Anordnung von Lagerpunkten der Lagereinheit 90a.Furthermore, the portable power tool 10a has at least the bearing unit 90a, which is provided to at least movably mount the pawl member 16a relative to the handle housing 32a. The bearing unit 90a is provided as a result of an actuation of the pawl member 16a, starting from a the connection portion 54a of the handle housing 32a facing the end of the pawl member 16a in the direction of another, the connection region 54a facing away, tangible end of the pawl element 16a, always a lifting movement of the pawl element 16a along to ensure a route with a value greater than zero. The bearing unit 90a has at least the lever bearing element 88a, which is provided to actuate a switch plunger element 102a of the switching element 50a of the switch unit 14a in response to a movement of the pawl element 16a ( Figures 3 . 4 and 5 ). The lever bearing element 88a is movably connected to the pawl element 16a at the end of the pawl element 16a facing the connection region 54a of the handle housing 32a. Furthermore, the bearing unit 90a has at least one further lever bearing element 100a, which is arranged movably on the pawl element 16a and movably on one of the handle housing shell elements 76a, 78a of the handle housing 32a. The lever bearing element 88a and the further lever bearing element 100a are aligned at least substantially parallel to one another. Due to the at least substantially parallel arrangement of the lever bearing element 88a and the further lever bearing element 100a, a parallel guidance of the pawl element 16a is realized as a result of an actuation of the pawl element 16a. The further, remote from the connection region 54a, the tangible end of the pawl element 16a is decoupled from an arrangement of bearing points of the bearing unit 90a.

Des Weiteren weist die Schalteinheit 14a zumindest ein weiteres Federelement 104a auf, das dazu vorgesehen ist, das Schaltklinkenelement 16a, mit einer Federkraft des weiteren Federelements 104a in Richtung einer Ausgangsstellung des Schaltklinkenelements 16a zu beaufschlagen. Das weitere Federelement 104a ist zu einer Bildung einer Totmannschaltungsfunktion der Schalteinheit 14a vorgesehen. Das weitere Federelement 104a ist dazu vorgesehen, infolge einer Einwirkung einer Federkraft auf das Schaltklinkenelement 16a eine Bewegung des Schaltklinkenelements 16a nach einer Aufhebung einer Einwirkung einer Betätigungskraft eines Bedieners auf das Schaltklinkenelement 16a in eine vom Handgriffgehäuse 32a abgewandte Richtung in eine Ausgangstellung des Schaltklinkenelements 16a zu ermöglichen. Hierbei wird das weitere Federelement 104a von einem das Schaltstößelelement 102a des Schaltelements 50a mit einer Federkraft beaufschlagenden Federelement des Schaltelements 50a gebildet. Somit übt das weitere Federelement 104a über das Hebellagerelement 88a, das infolge einer Bewegung des Schaltklinkenelements 16a in Richtung des Handgriffgehäuses 32a das Schaltstößelelement 102a des Schaltelements 50a betätigt, eine Federkraft auf das Schaltklinkenelement 16a aus. Hierdurch wird das Schaltklinkenelement 16a nach einer Aufhebung einer Einwirkung einer Betätigungskraft eines Bedieners in die vom Handgriffgehäuse 32a abgewandte Richtung bewegt. Eine Ausrichtung der Bedienfläche 22a des Schaltklinkenelements 16a relativ zum Handgriffgehäuse 32a wird mittels der Lagereinheit 90a infolge einer Bewegung des Schaltklinkenelements 16a relativ zum Handgriffgehäuse 32a zumindest im Wesentlichen beibehalten. Es wird somit mittels der Lagereinheit 90a eine gleichmäßige Hubbewegung über die gesamte Bedienfläche 22a des Schaltklinkenelements 16a in Richtung des Handgriffgehäuses 32a infolge einer Betätigung des Schaltklinkenelements 16a erreicht.Furthermore, the switching unit 14a has at least one further spring element 104a, which is provided to act on the pawl element 16a, with a spring force of the further spring element 104a in the direction of an initial position of the pawl element 16a. The further spring element 104a is provided for forming a deadman circuit function of the switching unit 14a. The further spring element 104a is provided to permit movement of the pawl member 16a upon release of an operator's operating force on the pawl member 16a in a direction away from the handle housing 32a to an output position of the pawl member 16a due to an action of a spring force on the pawl member 16a , In this case, the further spring element 104a is formed by a spring element of the switching element 50a which acts on the switch plunger element 102a of the switch element 50a with a spring force. Thus, the further spring element 104a exerts a spring force on the pawl element 16a via the lever bearing element 88a, which actuates the switch plunger element 102a of the switch element 50a as a result of a movement of the pawl element 16a in the direction of the handle housing 32a. As a result, the pawl member 16a is moved in the direction away from the handle housing 32a after canceling an action of an operating force of an operator. Alignment of the operating surface 22a of the pawl member 16a relative to the handle housing 32a is at least substantially maintained by the bearing unit 90a due to movement of the pawl member 16a relative to the handle housing 32a. It is thus achieved by means of the bearing unit 90a, a uniform lifting movement over the entire operating surface 22a of the pawl member 16a in the direction of the handle housing 32a due to actuation of the pawl member 16a.

Zu einer Inbetriebnahme der tragbaren Werkzeugmaschine 10a betätigt ein Bediener das Freigabeelement 18a oder das weitere Freigabeelement 28a ausgehend von der Verriegelungsstellung des Freigabeelements 18a und des weiteren Freigabeelements 28a, um die Bewegungssperre des Schaltklinkenelements 16a zu entriegeln (Figuren 2 bis 4). Infolge der Betätigung des Freigabeelements 18a oder des weiteren Freigabeelements 28a schwenken das Freigabeelement 18a und das weitere Freigabeelement 28a mittels der Bewegungsabhängigkeitseinheit 30a um die Freigabebewegungsachse 24a bzw. um die weitere Freigabebewegungsachse 80a in das Handgriffgehäuse 32a ein, bis der Betätigungsbereich 20a des Freigabeelements 18a und der Betätigungsbereich 34a des weiteren Freigabeelements 28a zumindest im Wesentlichen bündig mit der Außenfläche 46a des Handgriffgehäuses 32a abschließen (Figur 5). Das Freigabeelement 18a und das weitere Freigabeelement 28a befinden sich somit in der Entriegelungsstellung (Figuren 6 und 7). Das Freigabeelement 18a und das weitere Freigabeelement 28a werden von dem Bediener in der Entriegelungsstellung gehalten, bis das Sperrelement 94a und das weitere Sperrelement 106a infolge einer Bewegung des Schaltklinkenelements 16a in Richtung des Handgriffgehäuses 32a in die Entriegelungsaufnahmeausnehmungen 44a, 92a des Freigabeelements 18a und des weiteren Freigabeelements 28a eingetaucht sind (Figuren 6 und 7). Der Bediener muss nun lediglich eine Kraft aufbringen, die das Schaltklinkenelement 16a in einer Einschaltposition hält. Mittels einer Bewegung des Schaltklinkenelements 16a in Richtung des Handgriffgehäuses 32a in der Entriegelungsstellung des Freigabeelements 18a und des weiteren Freigabeelements 28a wird zudem mittels des Hebellagerelements 88a das Schaltstößelelement 102a des Schaltelements 50a betätigt (Figur 6).For putting the portable power tool 10a into operation, an operator operates the release member 18a or the further release member 28a from the lock position of the release member 18a and the further release member 28a to unlock the movement lock of the click member 16a (FIG. FIGS. 2 to 4 ). As a result of the actuation of the release element 18a or the further release element 28a, the release element 18a and the further release element 28a pivot about the release movement axis 24a or about the further release movement axis 80a into the handle housing 32a by means of the movement dependency unit 30a until the actuation region 20a of the release element 18a and the actuating region 34a of the further release element 28a are at least substantially flush with the outer surface 46a of the handle housing 32a ( FIG. 5 ). The release element 18a and the further release element 28a are thus in the unlocked position (FIG. FIGS. 6 and 7 ). The release member 18a and the further release member 28a are held by the operator in the unlocked position until the locking member 94a and the further locking member 106a due to movement of the pawl member 16a in the direction of the handle housing 32a in the Entriegelungsaufnahmeausnehmungen 44a, 92a of the release member 18a and the other release element 28a are immersed ( FIGS. 6 and 7 ). The operator now only has to apply a force which holds the pawl element 16a in a switch-on position. By means of a movement of the pawl element 16a in the direction of the handle housing 32a in the unlocked position of the release element 18a and the further release element 28a, the switch plunger element 102a of the switch element 50a is actuated by means of the lever bearing element 88a ( FIG. 6 ).

Das Freigabeelement 18a und das weitere Freigabeelement 28a werden mittels des Eingreifens des Sperrelements 94a und des weiteren Sperrelements 106a in die Entriegelungsaufnahmeausnehmungen 44a, 92a in der Entriegelungsstellung gehalten, bis eine Krafteinwirkung des Bedieners auf das Schaltklinkenelement 16a aufgehoben wird und das Schaltklinkenelement 16a infolge einer Federkraft des weiteren Federelements 104a in eine Ausgangsstellung bewegt wird. Hierdurch werden das Sperrelement 94a und das weitere Sperrelement 106a aus den Entriegelungsaufnahmeausnehmungen 44a, 92a herausbewegt. Das Freigabeelement 18a und das weitere Freigabeelement 28a werden mittels einer Federkraft des Federelements 42a in die Verriegelungsstellung bewegt. Somit ist nach einer Aufhebung einer Krafteinwirkung des Bedieners auf das Schaltklinkenelement 16a die Bewegungssperre des Schaltklinkenelements 16a nach einer Bewegung des Schaltklinkenelements 16a in eine Ausgangsstellung und einer Bewegung des Freigabeelements 18a und des weiteren Freigabeelements 28a in eine Verriegelungsstellung aktiv.The release member 18a and the further release member 28a are held by the engagement of the locking member 94a and the further locking member 106a in the Entriegelungsaufnahmeausnehmungen 44a, 92a in the unlocked position until a force of the operator on the pawl member 16a is released and the pawl member 16a due to a spring force of the further spring element 104a is moved to a starting position. As a result, the blocking element 94a and the further blocking element 106a are moved out of the Entriegelungsaufnahmeausnehmungen 44a, 92a. The release element 18a and the further release element 28a are moved by means of a spring force of the spring element 42a into the locking position. Thus, after a cancellation of a force of the operator on the pawl member 16a, the movement lock of the pawl member 16a after a movement of the pawl member 16a in an initial position and a movement of the release member 18a and the further release member 28a in a locked position is active.

Substantially identical components, features and functions are basically numbered by the same reference numerals. For distinguishing the embodiments the letters a and h are added to the reference numbers of the embodiments. The following description is limited essentially to the differences from the first embodiment in the FIGS. 1 to 9 , wherein with respect to the same components, features and functions on the description of the first embodiment in the FIGS. 1 to 9 can be referenced.

Figur 10 zeigt eine Detailansicht eines an einem Handgriffgehäuse 32b einer alternativen, als tragbare Werkzeugmaschine 10b ausgebildeten Werkzeugmaschine 10b angeordneten Freigabeelements 18b einer Schalteinheit 14b der tragbaren Werkzeugmaschine 10b in einem unbetätigten Zustand des Freigabeelements 18b. Die Werkzeugmaschine 10b weist einen zumindest im Wesentlichen analogen Aufbau zur Werkzeugmaschine 10a aus Figur 1 auf. Somit kann bezüglich einer Beschreibung bzw. Merkmalen der Werkzeugmaschine 10b des weiteren Ausführungsbeispiels zumindest im Wesentlichen auf die Beschreibung der Figur 1 verwiesen werden. Die Werkzeugmaschine 10b umfasst zumindest eine Schalteinheit 14b, die zumindest ein beweglich gelagertes Schaltklinkenelement 16b und zumindest ein Freigabeelement 18b zu einer Entriegelung einer Bewegungssperre des Schaltklinkenelements 16b aufweist. Das Freigabeelement 18b umfasst zumindest einen Betätigungsbereich 20b des Freigabeelements 18b, der zumindest teilweise seitlich neben einer Bedienfläche 22b des Schaltklinkenelements 16b angeordnet ist. Das Freigabeelement 18b ist in einem Bereich eines einem Anbindungsbereich 54b des Handgriffgehäuses 32b zugewandten Endes des Handgriffgehäuses 32b am Handgriffgehäuse 32b angeordnet. Zudem ist das Freigabeelement 18b vollständig außerhalb eines stielförmigen Griffbereichs 52b des Handgriffgehäuses 32b angeordnet. FIG. 10 11 shows a detailed view of a release element 18b of a switching unit 14b of the portable power tool 10b arranged on a handle housing 32b of an alternative machine tool 10b embodied as a portable machine tool 10b in an unactuated state of the release element 18b. The machine tool 10b has an at least substantially analogous structure to the machine tool 10a FIG. 1 on. Thus, with regard to a description or characteristics of the machine tool 10b of the further exemplary embodiment, at least substantially to the description of FIG FIG. 1 to get expelled. The machine tool 10b comprises at least one switching unit 14b, which has at least one movably mounted pawl element 16b and at least one release element 18b for unlocking a movement lock of the pawl element 16b. The release element 18b comprises at least one actuating region 20b of the release element 18b, which is arranged at least partially laterally next to a control surface 22b of the pawl element 16b. The release element 18b is arranged on the handle housing 32b in an area of an end of the handle housing 32b facing a connection region 54b of the handle housing 32b. In addition, the release element 18b is disposed completely outside of a handle-shaped handle portion 52b of the handle housing 32b.

Das Freigabeelement 18b ist schwenkbar um zumindest eine Freigabebewegungsachse 24b gelagert. Die Freigabebewegungsachse 24b ist somit als Freigabeschwenkachse ausgebildet. Das Freigabeelement 18b weist zumindest die Freigabebewegungsachse 24b auf, die in einer sich zumindest im Wesentlichen senkrecht zu einer Bewegungsachse 26b des Schaltklinkenelements 16b erstreckenden Ebene verläuft. Das Schaltklinkenelement 16b ist hierbei schwenkbar um eine als Schwenkachse 48b ausgebildete Bewegungsachse 26b des Schaltklinkenelements 16b gelagert. Die als Schwenkachse 48b ausgebildete Bewegungsachse 26b verläuft zumindest im Wesentlichen senkrecht zu einer Verbindungsebene des Handgriffgehäuses 32b, in der zwei Handgriffgehäuseschalenelemente 76b, 78b des Handgriffgehäuses 32b miteinander verbunden sind. Somit verläuft die Freigabebewegungsachse 24b zumindest im Wesentlichen parallel zur Verbindungsebene des Handgriffgehäuses 32b. Ferner verläuft die Freigabebewegungsachse 24b zumindest im Wesentlichen quer zu einer als Schwenkachse 48b ausgebildeten Bewegungsachse 26b des Schaltklinkenelements 16b. Hierbei ist das Schaltklinkenelement 16b mittels einer Lagereinheit 90b der tragbaren Werkzeugmaschine 10b an einem dem Anbindungsbereich 54b zugewandten Ende des Schaltklinkenelements 16b schwenkbar gelagert. Es ist jedoch auch denkbar, dass das Schaltklinkenelement 16b an einem dem Anbindungsbereich 54b abgewandten Ende des Schaltklinkenelements 16b mittels der Lagereinheit 90b schwenkbar gelagert ist oder translatorisch mittels der Lagereinheit 90b gelagert ist. Das Schaltklinkenelement 16b ist an einer Seite des Handgriffgehäuses 32b angeordnet, die bei einem Umgreifen des Handgriffgehäuses 32b zu einer ordnungsgemäßen Handhabung der tragbaren Werkzeugmaschine 10b einer Handinnenfläche einer Hand eines Bedieners (hier nicht näher dargestellt) zugewandt ist. Das Schaltklinkenelement 16b ist in jedem Betriebszustand an einer Seite des Handgriffgehäuses 32b angeordnet, die verschieden ist von einer weiteren Seite des Handgriffgehäuses 32b, die einer Abtriebsseite eines Abtriebsgehäuses (hier nicht näher dargestellt) zugewandt ist, aus der sich eine Spindel zu einem Antrieb bzw. zu einem Koppeln eines Bearbeitungswerkzeugs (hier nicht näher dargestellt) heraus erstreckt.The release element 18b is pivotally mounted about at least one release movement axis 24b. The release movement axis 24b is thus designed as a release pivot axis. The release element 18b has at least the release movement axis 24b which extends in a plane extending at least substantially perpendicular to a movement axis 26b of the pawl element 16b. The pawl element 16b is mounted pivotably about a movement axis 26b of the pawl element 16b designed as a pivot axis 48b. The movement axis 26b formed as a pivot axis 48b extends at least substantially perpendicular to a connection plane of the handle housing 32b, in which two handle housing shell elements 76b, 78b of the handle housing 32b are interconnected. Thus, the release movement axis 24b extends at least substantially parallel to the connection plane of the handle housing 32b. Furthermore, the release movement axis 24b runs at least substantially transversely to a movement axis 26b of the pawl element 16b which is designed as a pivot axis 48b. In this case, the pawl element 16b is pivotally mounted by means of a bearing unit 90b of the portable power tool 10b at an end of the pawl element 16b facing the connection region 54b. However, it is also conceivable for the pawl element 16b to be pivotably mounted on the end of the pawl element 16b remote from the connection region 54b by means of the bearing unit 90b, or to be mounted translationally by means of the bearing unit 90b. The pawl member 16b is disposed on a side of the handle housing 32b, which when gripping the handle housing 32b, faces proper handling of the portable power tool 10b of a palm of a hand of an operator (not shown here). The pawl member 16 b is disposed in each operating state on one side of the handle housing 32 b, which is different from another side of the handle housing 32 b, which faces an output side of a driven housing (not shown here), from which a spindle to a drive or to a coupling of a machining tool (not shown here) extends out.

Des Weiteren weist die Schalteinheit 14b zumindest ein weiteres Freigabeelement 28b auf. Das weitere Freigabeelement 28b ist ebenfalls im Bereich des dem Anbindungsbereich 54b zugewandten Endes des Handgriffgehäuses 32b am Handgriffgehäuse 32b angeordnet. Zudem ist das weitere Freigabeelement 28b ebenfalls vollständig außerhalb des stielförmigen Griffbereichs 52b am Handgriffgehäuse 32b angeordnet. Das weitere Freigabeelement 28b ist spiegelsymmetrisch zum Freigabeelement 18b angeordnet (Figur 4). Somit weist das weitere Freigabeelement 28b zumindest einen Betätigungsbereich 34b auf, der, bezogen auf eine sich zumindest im Wesentlichen senkrecht zur Bewegungsachse 26b des Schaltklinkenelements 16b erstreckende Ebene, spiegelsymmetrisch zum Betätigungsbereich 20b des Freigabeelements18b zumindest teilweise seitlich neben der Bedienfläche 22b des Schaltklinkenelements 16b angeordnet ist. Hierbei sind das Freigabeelement 18b und das weitere Freigabeelement 28b mittels einer Bewegungsabhängigkeitseinheit 30b der tragbaren Werkzeugmaschine 10b bewegungstechnisch miteinander gekoppelt.Furthermore, the switching unit 14b has at least one further release element 28b. The further release element 28b is likewise arranged on the handle housing 32b in the region of the end of the handle housing 32b facing the connection region 54b. In addition, the further release element 28b is likewise arranged completely outside the handle-shaped handle region 52b on the handle housing 32b. The further release element 28b is arranged mirror-symmetrically to the release element 18b ( FIG. 4 ). Thus, the further release element 28b has at least one actuation region 34b, which, with respect to a plane extending at least substantially perpendicular to the movement axis 26b of the pawl element 16b, is arranged mirror-symmetrically to the actuation region 20b of the release element 18b at least partially laterally adjacent to the control surface 22b of the pawl element 16b. Here, the release element 18b and the further release element 28b by means a motion dependency unit 30b of the portable power tool 10b coupled to each other in terms of motion.

Figur 11 zeigt eine Detailansicht eines an einem Handgriffgehäuse 32c einer alternativen, nicht erfindungsgemäßen, als tragbare Werkzeugmaschine 10c ausgebildeten Werkzeugmaschine 10c angeordneten Freigabeelements 18c einer Schalteinheit 14c der tragbaren Werkzeugmaschine 10c in einem unbetätigten Zustand des Freigabeelements 18c. Die Werkzeugmaschine 10c weist einen zumindest im Wesentlichen analogen Aufbau zur Werkzeugmaschine 10a aus Figur 1 auf. Somit kann bezüglich einer Beschreibung bzw. Merkmalen der Werkzeugmaschine 10c des weiteren Ausführungsbeispiels zumindest im Wesentlichen auf die Beschreibung der Figur 1 verwiesen werden. Die Werkzeugmaschine 10c umfasst zumindest eine Schalteinheit 14c, die zumindest ein beweglich gelagertes Schaltklinkenelement 16c und zumindest ein Freigabeelement 18c zu einer Entriegelung einer Bewegungssperre des Schaltklinkenelements 16c aufweist. Das Freigabeelement 18c umfasst zumindest einen Betätigungsbereich 20c des Freigabeelements 18c, der zumindest teilweise seitlich neben einer Bedienfläche 22c des Schaltklinkenelements 16c angeordnet ist. Das Freigabeelement 18c ist in einem Bereich eines einem Anbindungsbereich 54c des Handgriffgehäuses 32c zugewandten Endes des Handgriffgehäuses 32c am Handgriffgehäuse 32c angeordnet. Zudem ist das Freigabeelement 18c vollständig außerhalb eines stielförmigen Griffbereichs 52c des Handgriffgehäuses 32c angeordnet. FIG. 11 shows a detailed view of an on a handle housing 32c of an alternative, non-inventive, designed as a portable machine tool 10c machine tool 10c release element 18c of a switching unit 14c of the portable power tool 10c in an unactuated state of the release member 18c. The machine tool 10c has an at least substantially analogous structure to the machine tool 10a FIG. 1 on. Thus, with regard to a description or characteristics of the machine tool 10c of the further exemplary embodiment, at least substantially to the description of FIG FIG. 1 to get expelled. The machine tool 10c comprises at least one switching unit 14c which has at least one movably mounted pawl element 16c and at least one release element 18c for unlocking a movement lock of the pawl element 16c. The release element 18c comprises at least one actuating region 20c of the release element 18c, which is arranged at least partially laterally next to a control surface 22c of the pawl element 16c. The release member 18c is disposed on the handle housing 32c in an area of an end of the handle housing 32c facing a connection portion 54c of the handle housing 32c. In addition, the release member 18c is disposed entirely outside a handle-shaped handle portion 52c of the handle housing 32c.

Das Freigabeelement 18c ist schwenkbar um zumindest eine Freigabebewegungsachse 24c gelagert. Die Freigabebewegungsachse 24c ist somit als Freigabeschwenkachse ausgebildet. Das Freigabeelement 18c weist somit zumindest die Freigabebewegungsachse 24c auf, die zumindest im Wesentlichen parallel zu einer als Schwenkachse 48c ausgebildeten Bewegungsachse 26c des Schaltklinkenelements 16c verläuft (Figur 12). Die Bewegungsachse 26c des Schaltklinkenelements 16c verläuft zumindest im Wesentlichen senkrecht zu einer Verbindungsebene des Handgriffgehäuses 32b, in der zwei Handgriffgehäuseschalenelemente 76c, 78c verbindbar sind. Hierbei ist das Schaltklinkenelement 16c mittels einer Lagereinheit 90c der tragbaren Werkzeugmaschine 10c an einem einem Anbindungsbereich 54c des Handgriffgehäuses 32c zugewandten Ende des Schaltklinkenelements 16c schwenkbar gelagert. Es ist jedoch auch denkbar, dass das Schaltklinkenelement 16c an einem dem Anbindungsbereich 54c abgewandten Ende des Schaltklinkenelements 16c mittels der Lagereinheit 90c schwenkbar gelagert ist oder translatorisch mittels der Lagereinheit 90c gelagert ist.The release member 18c is pivotally supported about at least one release movement axis 24c. The release movement axis 24c is thus designed as a release pivot axis. The release element 18c thus has at least the release movement axis 24c, which extends at least substantially parallel to a movement axis 26c of the pawl element 16c designed as a pivot axis 48c ( FIG. 12 ). The movement axis 26c of the pawl member 16c extends at least substantially perpendicular to a connection plane of the handle housing 32b, in which two handle housing shell elements 76c, 78c are connectable. Here, the pawl member 16c is pivotally supported by a bearing unit 90c of the portable power tool 10c at an end of the pawl member 16c facing a connection portion 54c of the handle housing 32c. However, it is also conceivable that the pawl member 16 c at a the Connection region 54c facing away from the end of the pawl element 16c is pivotally mounted by means of the bearing unit 90c or is mounted translationally by means of the bearing unit 90c.

Des Weiteren weist die Schalteinheit 14c zumindest ein weiteres Freigabeelement 28c auf. Das weitere Freigabeelement 28c ist ebenfalls im Bereich des dem Anbindungsbereich 54c zugewandten Endes des Handgriffgehäuses 32c am Handgriffgehäuse 32c angeordnet. Zudem ist das weitere Freigabeelement 28c ebenfalls vollständig außerhalb des stielförmigen Griffbereichs 52c am Handgriffgehäuse 32c angeordnet. Das weitere Freigabeelement 28c ist spiegelsymmetrisch zum Freigabeelement 18c angeordnet. Somit weist das weitere Freigabeelement 28c zumindest einen Betätigungsbereich 34c auf, der, bezogen auf eine sich zumindest im Wesentlichen senkrecht zur Bewegungsachse 26c des Schaltklinkenelements 16c erstreckende Ebene, spiegelsymmetrisch zum Betätigungsbereich 20c des Freigabeelements18c zumindest teilweise seitlich neben der Bedienfläche 22c des Schaltklinkenelements 16c angeordnet ist. Hierbei sind das Freigabeelement 18c und das weitere Freigabeelement 28c mittels einer Bewegungsabhängigkeitseinheit 30c der tragbaren Werkzeugmaschine 10c bewegungstechnisch miteinander gekoppelt. Die Bewegungsabhängigkeitseinheit 30c koppelt hierbei das Freigabeelement 18c und das weitere Freigabeelement 28c starr miteinander. Das Freigabeelement 18c und das weitere Freigabeelement 28c werden somit bei einer Betätigung des Freigabeelements 18c oder des weiteren Freigabeelements 28c stets zusammen in eine gleiche Richtung bewegt. Hierbei werden das Freigabeelement 18c und das weitere Freigabeelement 28c infolge einer Betätigung des Freigabeelements 18c oder des weiteren Freigabeelements 28c in eine dem Handgriffgehäuse 32c zugewandte Richtung mittels der Bewegungsabhängigkeitseinheit 30c in eine dem Handgriffgehäuse 32c zugewandte Richtung bewegt.Furthermore, the switching unit 14c has at least one further release element 28c. The further release element 28c is likewise arranged on the handle housing 32c in the region of the end of the handle housing 32c facing the connection region 54c. In addition, the further release element 28c is also arranged completely outside the handle-shaped handle region 52c on the handle housing 32c. The further release element 28c is arranged mirror-symmetrically to the release element 18c. Thus, the further release element 28c has at least one actuation region 34c, which, with respect to a plane extending at least substantially perpendicular to the movement axis 26c of the pawl element 16c, is arranged mirror-symmetrically to the actuation region 20c of the release element 18c at least partially laterally adjacent to the control surface 22c of the pawl element 16c. In this case, the release element 18c and the further release element 28c are coupled to one another by means of a movement-dependent unit 30c of the portable power tool 10c. In this case, the movement-dependent unit 30c rigidly couples the release element 18c and the further release element 28c to one another. The release element 18c and the further release element 28c are thus always moved together in an identical direction upon actuation of the release element 18c or the further release element 28c. In this case, the release member 18c and the further release member 28c are moved in a direction toward the handle housing 32c by the operation of the release member 18c or the further release member 28c in a direction toward the handle housing 32c by means of the movement dependency unit 30c.

Figur 13 zeigt eine Detailansicht eines an einem Handgriffgehäuse 32d einer alternativen, nicht erfindungsgemäßen als tragbare Werkzeugmaschine 10d ausgebildeten Werkzeugmaschine 10d angeordneten Freigabeelements 18d einer Schalteinheit 14d der tragbaren Werkzeugmaschine 10d in einem unbetätigten Zustand des Freigabeelements 18d. Die Werkzeugmaschine 10d weist einen zumindest im Wesentlichen analogen Aufbau zur Werkzeugmaschine 10a aus Figur 1 auf. Somit kann bezüglich einer Beschreibung bzw. Merkmalen der Werkzeugmaschine 10d des weiteren Ausführungsbeispiels zumindest im Wesentlichen auf die Beschreibung der Figur 1 verwiesen werden. Die Werkzeugmaschine 10d umfasst zumindest eine Schalteinheit 14d, die zumindest ein beweglich gelagertes Schaltklinkenelement (hier nicht näher dargestellt) und zumindest ein Freigabeelement 18d zu einer Entriegelung einer Bewegungssperre des Schaltklinkenelements 16d aufweist. Das Freigabeelement 18d umfasst zumindest einen Betätigungsbereich 20d des Freigabeelements 18d, der zumindest teilweise seitlich neben einer Bedienfläche (hier nicht näher dargestellt) des Schaltklinkenelements angeordnet ist. Das Freigabeelement 18d ist vollständig an einem stielförmigen Griffbereich 52d des Handgriffgehäuses 32d angeordnet. FIG. 13 shows a detailed view of an on a handle housing 32d of an alternative, not according to the invention as a portable machine tool 10d trained machine tool 10d arranged release element 18d a switching unit 14d of the portable power tool 10d in an unactuated state of the release element 18d. The machine tool 10d has an at least substantially analogous construction to the machine tool 10a FIG. 1 on. Thus, with respect to a description or characteristics of the machine tool 10d of the Another embodiment, at least substantially to the description of FIG. 1 to get expelled. The machine tool 10d comprises at least one switching unit 14d which has at least one movably mounted pawl element (not shown here in detail) and at least one release element 18d for unlocking a movement lock of the pawl element 16d. The release element 18d comprises at least one actuating region 20d of the release element 18d, which is arranged at least partially laterally next to a control surface (not shown here in detail) of the pawl element. The release member 18d is fully disposed on a handle-shaped handle portion 52d of the handle housing 32d.

Das Freigabeelement 18d ist schwenkbar um eine Freigabebewegungsachse 24d des Freigabeelements 18d gelagert. Das Freigabeelement 18d weist zumindest die Freigabebewegungsachse 24d auf, die in einer sich zumindest im Wesentlichen senkrecht zu einer Bewegungsachse 26d des Schaltklinkenelements 16d erstreckenden Ebene verläuft. Es ist jedoch auch denkbar, dass das Freigabeelement 18d alternativ zur schwenkbaren Lagerung translatorisch entlang einer zumindest im Wesentlichen parallel zur Bewegungsachse 26d des Schaltklinkenelements verlaufenden Freigabebewegungsachse 24d beweglich gelagert ist. Das Schaltklinkenelement 16d ist hierbei schwenkbar um eine als Schwenkachse 48d ausgebildete Bewegungsachse 26d des Schaltklinkenelements gelagert. Die als Schwenkachse 48d ausgebildete Bewegungsachse 26d verläuft zumindest im Wesentlichen senkrecht zu einer Verbindungsebene des Handgriffgehäuses 32d, in der zwei Handgriffgehäuseschalenelemente 76d, 78d des Handgriffgehäuses 32d miteinander verbunden sind. Des Weiteren weist die Schalteinheit 14d zumindest ein weiteres Freigabeelement 28d auf. Das weitere Freigabeelement 28d ist ebenfalls vollständig in dem stielförmigen Griffbereich 52d am Handgriffgehäuse 32d angeordnet. Das weitere Freigabeelement 28d ist spiegelsymmetrisch zum Freigabeelement 18d am Handgriffgehäuse 32d angeordnet. Hierbei sind das Freigabeelement 18d und das weitere Freigabeelement 28d mittels einer Bewegungsabhängigkeitseinheit 30d der tragbaren Werkzeugmaschine 10d bewegungstechnisch miteinander gekoppelt.The release member 18d is pivotally supported about a release movement axis 24d of the release member 18d. The release element 18d has at least the release movement axis 24d extending in a plane extending at least substantially perpendicular to a movement axis 26d of the pawl element 16d.
